    Hello! I (tried, at least) converted an old laptop to a Debian home server, and I was trying to set up duckdns.org and to enable port forwarding on my router. internet connection was working, I installed packages, docker, immich, etc, and then suddenly (I don’t know exactly when) it refuses to connect to the internet. It does connect to local addresses (I can ssh into it) but `ping google.com` and any other internet-involving command fail. I had set up a rule on the router to forward port 80 to the device’s port 80, but I then removed the rule and it still does not connect to the internet. I rebooted the router but nothing changed. Any idea what could be? the router is a Vodafone router.\n

      Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
      \n
      Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
      \n
      ### Rules\n
      \n
      - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n

    +body: """
      Hello! I (tried, at least) converted an old laptop to a Debian home server, and I was trying to set up duckdns.org and to enable port forwarding on my router. internet connection was working, I installed packages, docker, immich, etc, and then suddenly (I don’t know exactly when) it refuses to connect to the internet. It does connect to local addresses (I can ssh into it) but `ping google.com` and any other internet-involving command fail. I had set up a rule on the router to forward port 80 to the device’s port 80, but I then removed the rule and it still does not connect to the internet. I rebooted the router but nothing changed. Any idea what could be? the router is a Vodafone router.\n
      \n
      ![](https://lemmy.kde.social/pictrs/image/12682af4-71fe-4f72-bd99-82e613fbf507.png)\n
      \n
      I changed the hostname to debianserver but on the router it is still written debian. Also, it’s the only device with unknown ipv6\n
      \n
      thanks in advance!\n
      \n
      EDIT: I rebooted again the server, and now ipv6 is not unknown anymore, and the hostname is correct. however, it still does not connect to the internet\n
      \n
      ![](https://lemmy.kde.social/pictrs/image/b93cd90b-46ba-43d3-89e3-a5d02c0f1e07.png)\n
      \n
      EDIT 2:\n
      \n
      only one device (debianserver) has this problem, other devices work as before\n
      \n
      EDIT 3:\n
      \n
      I don’t know if it’s useful or not, but if I boot a live debian USB in the server internet works\n
      \n
      SOLUTION: aaaaand no it does not work, after restarting docker it seems to work because all the brodges are yet to be created and it takes some time, after like 30 seconds it does not work as before :(\n
      \n
      - edit the file `/lib/systemd/system/docker.service`\n
      - append the flag `–bip=192.168.3.1/24` to `ExecStart=…`\n
      - `systemctl daemon-reload`\n
      - `systemctl restart docker`\n
      \n
      docker was the fucker that messed everything up and made me lose a few hours!\n
      \n
      EDIT 4:\n
      \n
      it seems that `ip route flush 0/0` restores the internet connectivity until reboot… I don’t know what does this means but can be a temporary workaround I guess? I really have no idea how to solve this\n
      \n
      FINAL EDIT: I gave up. I removed debian and installed fedora, and now it all works like a charm

      Hello! I (tried, at least) converted an old laptop to a Debian home server, and I was trying to set up duckdns.org and to enable port forwarding on my router. internet connection was working, I installed packages, docker, immich, etc, and then suddenly (I don’t know exactly when) it refuses to connect to the internet. It does connect to local addresses (I can ssh into it) but `ping google.com` and any other internet-involving command fail. I had set up a rule on the router to forward port 80 to the device’s port 80, but I then removed the rule and it still does not connect to the internet. I rebooted the router but nothing changed. Any idea what could be? the router is a Vodafone router.\n

      \n
      I changed the hostname to debianserver but on the router it is still written debian. Also, it’s the only device with unknown ipv6\n
      \n
      thanks in advance!\n
      \n
      EDIT: I rebooted again the server, and now ipv6 is not unknown anymore, and the hostname is correct. however, it still does not connect to the internet\n
      \n
      ![](https://lemmy.kde.social/pictrs/image/b93cd90b-46ba-43d3-89e3-a5d02c0f1e07.png)\n
      \n
      EDIT 2:\n
      \n
      only one device (debianserver) has this problem, other devices work as before\n
      \n
      EDIT 3:\n
      \n
      I don’t know if it’s useful or not, but if I boot a live debian USB in the server internet works\n
      \n
      SOLUTION: aaaaand no it does not work, after restarting docker it seems to work because all the brodges are yet to be created and it takes some time, after like 30 seconds it does not work as before :(\n
      \n
      - edit the file `/lib/systemd/system/docker.service`\n
      - append the flag `–bip=192.168.3.1/24` to `ExecStart=…`\n
      - `systemctl daemon-reload`\n
      - `systemctl restart docker`\n
      \n
      docker was the fucker that messed everything up and made me lose a few hours!\n
      \n
      EDIT 4:\n
      \n
      it seems that `ip route flush 0/0` restores the internet connectivity until reboot… I don’t know what does this means but can be a temporary workaround I guess? I really have no idea how to solve this\n
      \n
      FINAL EDIT: I gave up. I removed debian and installed fedora, and now it all works like a charm

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n

    +title: "[not solved] I think I messed something up in the router settings but cannot understand what... now I have no internet connection"
    +url: null
    +body: """
      Hello! I (tried, at least) converted an old laptop to a Debian home server, and I was trying to set up duckdns.org and to enable port forwarding on my router. internet connection was working, I installed packages, docker, immich, etc, and then suddenly (I don’t know exactly when) it refuses to connect to the internet. It does connect to local addresses (I can ssh into it) but `ping google.com` and any other internet-involving command fail. I had set up a rule on the router to forward port 80 to the device’s port 80, but I then removed the rule and it still does not connect to the internet. I rebooted the router but nothing changed. Any idea what could be? the router is a Vodafone router.\n
      \n
      ![](https://lemmy.kde.social/pictrs/image/12682af4-71fe-4f72-bd99-82e613fbf507.png)\n
      \n
      I changed the hostname to debianserver but on the router it is still written debian. Also, it’s the only device with unknown ipv6\n
      \n
      thanks in advance!\n
      \n
      EDIT: I rebooted again the server, and now ipv6 is not unknown anymore, and the hostname is correct. however, it still does not connect to the internet\n
      \n
      ![](https://lemmy.kde.social/pictrs/image/b93cd90b-46ba-43d3-89e3-a5d02c0f1e07.png)\n
      \n
      EDIT 2:\n
      \n
      only one device (debianserver) has this problem, other devices work as before\n
      \n
      EDIT 3:\n
      \n
      I don’t know if it’s useful or not, but if I boot a live debian USB in the server internet works\n
      \n
      SOLUTION: aaaaand no it does not work, after restarting docker it seems to work because all the brodges are yet to be created and it takes some time, after like 30 seconds it does not work as before :(\n
      \n
      - edit the file `/lib/systemd/system/docker.service`\n
      - append the flag `–bip=192.168.3.1/24` to `ExecStart=…`\n
      - `systemctl daemon-reload`\n
      - `systemctl restart docker`\n
      \n
      docker was the fucker that messed everything up and made me lose a few hours!\n
      \n
      EDIT 4:\n
      \n
      it seems that `ip route flush 0/0` restores the internet connectivity until reboot… I don’t know what does this means but can be a temporary workaround I guess? I really have no idea how to solve this\n
      \n
      FINAL EDIT: I gave up. I removed debian and installed fedora, and now it all works like a charm

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n

    +title: "[not solved] I think I messed something up in the router settings but cannot understand what... now I have no internet connection"
    +url: null
    +body: """
      Hello! I (tried, at least) converted an old laptop to a Debian home server, and I was trying to set up duckdns.org and to enable port forwarding on my router. internet connection was working, I installed packages, docker, immich, etc, and then suddenly (I don’t know exactly when) it refuses to connect to the internet. It does connect to local addresses (I can ssh into it) but `ping google.com` and any other internet-involving command fail. I had set up a rule on the router to forward port 80 to the device’s port 80, but I then removed the rule and it still does not connect to the internet. I rebooted the router but nothing changed. Any idea what could be? the router is a Vodafone router.\n
      \n
      ![](https://lemmy.kde.social/pictrs/image/12682af4-71fe-4f72-bd99-82e613fbf507.png)\n
      \n
      I changed the hostname to debianserver but on the router it is still written debian. Also, it’s the only device with unknown ipv6\n
      \n
      thanks in advance!\n
      \n
      EDIT: I rebooted again the server, and now ipv6 is not unknown anymore, and the hostname is correct. however, it still does not connect to the internet\n
      \n
      ![](https://lemmy.kde.social/pictrs/image/b93cd90b-46ba-43d3-89e3-a5d02c0f1e07.png)\n
      \n
      EDIT 2:\n
      \n
      only one device (debianserver) has this problem, other devices work as before\n
      \n
      EDIT 3:\n
      \n
      I don’t know if it’s useful or not, but if I boot a live debian USB in the server internet works\n
      \n
      SOLUTION: aaaaand no it does not work, after restarting docker it seems to work because all the brodges are yet to be created and it takes some time, after like 30 seconds it does not work as before :(\n
      \n
      - edit the file `/lib/systemd/system/docker.service`\n
      - append the flag `–bip=192.168.3.1/24` to `ExecStart=…`\n
      - `systemctl daemon-reload`\n
      - `systemctl restart docker`\n
      \n
      docker was the fucker that messed everything up and made me lose a few hours!\n
      \n
      EDIT 4:\n
      \n
      it seems that `ip route flush 0/0` restores the internet connectivity until reboot… I don’t know what does this means but can be a temporary workaround I guess? I really have no idea how to solve this\n
      \n
      FINAL EDIT: I gave up. I removed debian and installed fedora, and now it all works like a charm

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n

    +title: "[not solved] I think I messed something up in the router settings but cannot understand what... now I have no internet connection"
    +url: null
    +body: """
      Hello! I (tried, at least) converted an old laptop to a Debian home server, and I was trying to set up duckdns.org and to enable port forwarding on my router. internet connection was working, I installed packages, docker, immich, etc, and then suddenly (I don’t know exactly when) it refuses to connect to the internet. It does connect to local addresses (I can ssh into it) but `ping google.com` and any other internet-involving command fail. I had set up a rule on the router to forward port 80 to the device’s port 80, but I then removed the rule and it still does not connect to the internet. I rebooted the router but nothing changed. Any idea what could be? the router is a Vodafone router.\n
      \n
      ![](https://lemmy.kde.social/pictrs/image/12682af4-71fe-4f72-bd99-82e613fbf507.png)\n
      \n
      I changed the hostname to debianserver but on the router it is still written debian. Also, it’s the only device with unknown ipv6\n
      \n
      thanks in advance!\n
      \n
      EDIT: I rebooted again the server, and now ipv6 is not unknown anymore, and the hostname is correct. however, it still does not connect to the internet\n
      \n
      ![](https://lemmy.kde.social/pictrs/image/b93cd90b-46ba-43d3-89e3-a5d02c0f1e07.png)\n
      \n
      EDIT 2:\n
      \n
      only one device (debianserver) has this problem, other devices work as before\n
      \n
      EDIT 3:\n
      \n
      I don’t know if it’s useful or not, but if I boot a live debian USB in the server internet works\n
      \n
      SOLUTION: aaaaand no it does not work, after restarting docker it seems to work because all the brodges are yet to be created and it takes some time, after like 30 seconds it does not work as before :(\n
      \n
      - edit the file `/lib/systemd/system/docker.service`\n
      - append the flag `–bip=192.168.3.1/24` to `ExecStart=…`\n
      - `systemctl daemon-reload`\n
      - `systemctl restart docker`\n
      \n
      docker was the fucker that messed everything up and made me lose a few hours!\n
      \n
      EDIT 4:\n
      \n
      it seems that `ip route flush 0/0` restores the internet connectivity until reboot… I don’t know what does this means but can be a temporary workaround I guess? I really have no idea how to solve this\n
      \n
      FINAL EDIT: I gave up. I removed debian and installed fedora, and now it all works like a charm

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n

    +url: null
    +body: """
      Hello! I (tried, at least) converted an old laptop to a Debian home server, and I was trying to set up duckdns.org and to enable port forwarding on my router. internet connection was working, I installed packages, docker, immich, etc, and then suddenly (I don’t know exactly when) it refuses to connect to the internet. It does connect to local addresses (I can ssh into it) but `ping google.com` and any other internet-involving command fail. I had set up a rule on the router to forward port 80 to the device’s port 80, but I then removed the rule and it still does not connect to the internet. I rebooted the router but nothing changed. Any idea what could be? the router is a Vodafone router.\n
      \n
      ![](https://lemmy.kde.social/pictrs/image/12682af4-71fe-4f72-bd99-82e613fbf507.png)\n
      \n
      I changed the hostname to debianserver but on the router it is still written debian. Also, it’s the only device with unknown ipv6\n
      \n
      thanks in advance!\n
      \n
      EDIT: I rebooted again the server, and now ipv6 is not unknown anymore, and the hostname is correct. however, it still does not connect to the internet\n
      \n
      ![](https://lemmy.kde.social/pictrs/image/b93cd90b-46ba-43d3-89e3-a5d02c0f1e07.png)\n
      \n
      EDIT 2:\n
      \n
      only one device (debianserver) has this problem, other devices work as before\n
      \n
      EDIT 3:\n
      \n
      I don’t know if it’s useful or not, but if I boot a live debian USB in the server internet works\n
      \n
      SOLUTION: aaaaand no it does not work, after restarting docker it seems to work because all the brodges are yet to be created and it takes some time, after like 30 seconds it does not work as before :(\n
      \n
      - edit the file `/lib/systemd/system/docker.service`\n
      - append the flag `–bip=192.168.3.1/24` to `ExecStart=…`\n
      - `systemctl daemon-reload`\n
      - `systemctl restart docker`\n
      \n
      docker was the fucker that messed everything up and made me lose a few hours!\n
      \n
      EDIT 4:\n
      \n
      it seems that `ip route flush 0/0` restores the internet connectivity until reboot… I don’t know what does this means but can be a temporary workaround I guess? I really have no idea how to solve this\n
      \n
      FINAL EDIT: I gave up. I removed debian and installed fedora, and now it all works like a charm

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n

    +url: null
    +body: """
      Hello! I (tried, at least) converted an old laptop to a Debian home server, and I was trying to set up duckdns.org and to enable port forwarding on my router. internet connection was working, I installed packages, docker, immich, etc, and then suddenly (I don’t know exactly when) it refuses to connect to the internet. It does connect to local addresses (I can ssh into it) but `ping google.com` and any other internet-involving command fail. I had set up a rule on the router to forward port 80 to the device’s port 80, but I then removed the rule and it still does not connect to the internet. I rebooted the router but nothing changed. Any idea what could be? the router is a Vodafone router.\n
      \n
      ![](https://lemmy.kde.social/pictrs/image/12682af4-71fe-4f72-bd99-82e613fbf507.png)\n
      \n
      I changed the hostname to debianserver but on the router it is still written debian. Also, it’s the only device with unknown ipv6\n
      \n
      thanks in advance!\n
      \n
      EDIT: I rebooted again the server, and now ipv6 is not unknown anymore, and the hostname is correct. however, it still does not connect to the internet\n

      \n
      EDIT 2:\n
      \n
      only one device (debianserver) has this problem, other devices work as before\n
      \n
      EDIT 3:\n
      \n
      I don’t know if it’s useful or not, but if I boot a live debian USB in the server internet works\n
      \n
      SOLUTION: aaaaand no it does not work, after restarting docker it seems to work because all the brodges are yet to be created and it takes some time, after like 30 seconds it does not work as before :(\n
      \n
      - edit the file `/lib/systemd/system/docker.service`\n
      - append the flag `–bip=192.168.3.1/24` to `ExecStart=…`\n
      - `systemctl daemon-reload`\n
      - `systemctl restart docker`\n
      \n
      docker was the fucker that messed everything up and made me lose a few hours!\n
      \n
      EDIT 4:\n
      \n
      it seems that `ip route flush 0/0` restores the internet connectivity until reboot… I don’t know what does this means but can be a temporary workaround I guess? I really have no idea how to solve this\n
      \n
      FINAL EDIT: I gave up. I removed debian and installed fedora, and now it all works like a charm

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n

      Hello! I (tried, at least) converted an old laptop to a Debian home server, and I was trying to set up duckdns.org and to enable port forwarding on my router. internet connection was working, I installed packages, docker, immich, etc, and then suddenly (I don’t know exactly when) it refuses to connect to the internet. It does connect to local addresses (I can ssh into it) but `ping google.com` and any other internet-involving command fail. I had set up a rule on the router to forward port 80 to the device’s port 80, but I then removed the rule and it still does not connect to the internet. I rebooted the router but nothing changed. Any idea what could be? the router is a Vodafone router.\n
      \n

      \n
      I changed the hostname to debianserver but on the router it is still written debian. Also, it’s the only device with unknown ipv6\n
      \n
      thanks in advance!\n
      \n
      EDIT: I rebooted again the server, and now ipv6 is not unknown anymore, and the hostname is correct. however, it still does not connect to the internet\n

      \n
      EDIT 2:\n
      \n
      only one device (debianserver) has this problem, other devices work as before\n
      \n
      EDIT 3:\n
      \n
      I don’t know if it’s useful or not, but if I boot a live debian USB in the server internet works\n
      \n
      SOLUTION: aaaaand no it does not work, after restarting docker it seems to work because all the brodges are yet to be created and it takes some time, after like 30 seconds it does not work as before :(\n
      \n
      - edit the file `/lib/systemd/system/docker.service`\n
      - append the flag `–bip=192.168.3.1/24` to `ExecStart=…`\n
      - `systemctl daemon-reload`\n
      - `systemctl restart docker`\n
      \n
      docker was the fucker that messed everything up and made me lose a few hours!\n
      \n
      EDIT 4:\n
      \n
      it seems that `ip route flush 0/0` restores the internet connectivity until reboot… I don’t know what does this means but can be a temporary workaround I guess? I really have no idea how to solve this\n
      \n
      FINAL EDIT: I gave up. I removed debian and installed fedora, and now it all works like a charm

    This is kind of a nutty network config. It looks like docker is setting up extra default routes, which I could easily see fouling everything up. As a first experiment (warning, this may ruin your networking until the next reboot):\n
    \n
    ```\n
    ip route flush 0/0\n
    ip route add default via 192.168.1.1 dev enp1s0\n
    \n
    ```\n
    \n
    ... and see if that makes things work (start with `ping 192.168.1.1` and `ping 8.8.8.8`). If that solves the problem, then I think something about your docker config is adding stuff to your networking that's causing the problem; maybe remove/disable docker completely and then re-add docker things one at a time to see where the problem comes in.

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n
        - No NSFW content\n
        - No hate speech, bigotry, etc\n

    +title: "[not solved] I think I messed something up in the router settings but cannot understand what... now I have no internet connection"
    +url: null
    +body: """
      Hello! I (tried, at least) converted an old laptop to a Debian home server, and I was trying to set up duckdns.org and to enable port forwarding on my router. internet connection was working, I installed packages, docker, immich, etc, and then suddenly (I don’t know exactly when) it refuses to connect to the internet. It does connect to local addresses (I can ssh into it) but `ping google.com` and any other internet-involving command fail. I had set up a rule on the router to forward port 80 to the device’s port 80, but I then removed the rule and it still does not connect to the internet. I rebooted the router but nothing changed. Any idea what could be? the router is a Vodafone router.\n
      \n
      ![](https://lemmy.kde.social/pictrs/image/12682af4-71fe-4f72-bd99-82e613fbf507.png)\n
      \n
      I changed the hostname to debianserver but on the router it is still written debian. Also, it’s the only device with unknown ipv6\n
      \n
      thanks in advance!\n
      \n
      EDIT: I rebooted again the server, and now ipv6 is not unknown anymore, and the hostname is correct. however, it still does not connect to the internet\n
      \n
      ![](https://lemmy.kde.social/pictrs/image/b93cd90b-46ba-43d3-89e3-a5d02c0f1e07.png)\n
      \n
      EDIT 2:\n
      \n
      only one device (debianserver) has this problem, other devices work as before\n
      \n
      EDIT 3:\n
      \n
      I don’t know if it’s useful or not, but if I boot a live debian USB in the server internet works\n
      \n
      SOLUTION: aaaaand no it does not work, after restarting docker it seems to work because all the brodges are yet to be created and it takes some time, after like 30 seconds it does not work as before :(\n
      \n
      - edit the file `/lib/systemd/system/docker.service`\n
      - append the flag `–bip=192.168.3.1/24` to `ExecStart=…`\n
      - `systemctl daemon-reload`\n
      - `systemctl restart docker`\n
      \n
      docker was the fucker that messed everything up and made me lose a few hours!\n
      \n
      EDIT 4:\n
      \n
      it seems that `ip route flush 0/0` restores the internet connectivity until reboot… I don’t know what does this means but can be a temporary workaround I guess? I really have no idea how to solve this\n
      \n
      FINAL EDIT: I gave up. I removed debian and installed fedora, and now it all works like a charm

    This is kind of a nutty network config. It looks like docker is setting up extra default routes, which I could easily see fouling everything up. As a first experiment (warning, this may ruin your networking until the next reboot):\n
    \n
    ```\n
    ip route flush 0/0\n
    ip route add default via 192.168.1.1 dev enp1s0\n
    \n
    ```\n
    \n
    ... and see if that makes things work (start with `ping 192.168.1.1` and `ping 8.8.8.8`). If that solves the problem, then I think something about your docker config is adding stuff to your networking that's causing the problem; maybe remove/disable docker completely and then re-add docker things one at a time to see where the problem comes in.

        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n

    +title: "[not solved] I think I messed something up in the router settings but cannot understand what... now I have no internet connection"
    +url: null
    +body: """
      Hello! I (tried, at least) converted an old laptop to a Debian home server, and I was trying to set up duckdns.org and to enable port forwarding on my router. internet connection was working, I installed packages, docker, immich, etc, and then suddenly (I don’t know exactly when) it refuses to connect to the internet. It does connect to local addresses (I can ssh into it) but `ping google.com` and any other internet-involving command fail. I had set up a rule on the router to forward port 80 to the device’s port 80, but I then removed the rule and it still does not connect to the internet. I rebooted the router but nothing changed. Any idea what could be? the router is a Vodafone router.\n
      \n
      ![](https://lemmy.kde.social/pictrs/image/12682af4-71fe-4f72-bd99-82e613fbf507.png)\n
      \n
      I changed the hostname to debianserver but on the router it is still written debian. Also, it’s the only device with unknown ipv6\n
      \n
      thanks in advance!\n
      \n
      EDIT: I rebooted again the server, and now ipv6 is not unknown anymore, and the hostname is correct. however, it still does not connect to the internet\n
      \n
      ![](https://lemmy.kde.social/pictrs/image/b93cd90b-46ba-43d3-89e3-a5d02c0f1e07.png)\n
      \n
      EDIT 2:\n
      \n
      only one device (debianserver) has this problem, other devices work as before\n
      \n
      EDIT 3:\n
      \n
      I don’t know if it’s useful or not, but if I boot a live debian USB in the server internet works\n
      \n
      SOLUTION: aaaaand no it does not work, after restarting docker it seems to work because all the brodges are yet to be created and it takes some time, after like 30 seconds it does not work as before :(\n
      \n
      - edit the file `/lib/systemd/system/docker.service`\n
      - append the flag `–bip=192.168.3.1/24` to `ExecStart=…`\n
      - `systemctl daemon-reload`\n
      - `systemctl restart docker`\n
      \n
      docker was the fucker that messed everything up and made me lose a few hours!\n
      \n
      EDIT 4:\n
      \n
      it seems that `ip route flush 0/0` restores the internet connectivity until reboot… I don’t know what does this means but can be a temporary workaround I guess? I really have no idea how to solve this\n
      \n
      FINAL EDIT: I gave up. I removed debian and installed fedora, and now it all works like a charm

    This is kind of a nutty network config. It looks like docker is setting up extra default routes, which I could easily see fouling everything up. As a first experiment (warning, this may ruin your networking until the next reboot):\n
    \n
    ```\n
    ip route flush 0/0\n
    ip route add default via 192.168.1.1 dev enp1s0\n
    \n
    ```\n
    \n
    ... and see if that makes things work (start with `ping 192.168.1.1` and `ping 8.8.8.8`). If that solves the problem, then I think something about your docker config is adding stuff to your networking that's causing the problem; maybe remove/disable docker completely and then re-add docker things one at a time to see where the problem comes in.

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n

    +title: "[not solved] I think I messed something up in the router settings but cannot understand what... now I have no internet connection"
    +url: null
    +body: """
      Hello! I (tried, at least) converted an old laptop to a Debian home server, and I was trying to set up duckdns.org and to enable port forwarding on my router. internet connection was working, I installed packages, docker, immich, etc, and then suddenly (I don’t know exactly when) it refuses to connect to the internet. It does connect to local addresses (I can ssh into it) but `ping google.com` and any other internet-involving command fail. I had set up a rule on the router to forward port 80 to the device’s port 80, but I then removed the rule and it still does not connect to the internet. I rebooted the router but nothing changed. Any idea what could be? the router is a Vodafone router.\n
      \n
      ![](https://lemmy.kde.social/pictrs/image/12682af4-71fe-4f72-bd99-82e613fbf507.png)\n
      \n
      I changed the hostname to debianserver but on the router it is still written debian. Also, it’s the only device with unknown ipv6\n
      \n
      thanks in advance!\n
      \n
      EDIT: I rebooted again the server, and now ipv6 is not unknown anymore, and the hostname is correct. however, it still does not connect to the internet\n
      \n
      ![](https://lemmy.kde.social/pictrs/image/b93cd90b-46ba-43d3-89e3-a5d02c0f1e07.png)\n
      \n
      EDIT 2:\n
      \n
      only one device (debianserver) has this problem, other devices work as before\n
      \n
      EDIT 3:\n
      \n
      I don’t know if it’s useful or not, but if I boot a live debian USB in the server internet works\n
      \n
      SOLUTION: aaaaand no it does not work, after restarting docker it seems to work because all the brodges are yet to be created and it takes some time, after like 30 seconds it does not work as before :(\n
      \n
      - edit the file `/lib/systemd/system/docker.service`\n
      - append the flag `–bip=192.168.3.1/24` to `ExecStart=…`\n
      - `systemctl daemon-reload`\n
      - `systemctl restart docker`\n
      \n
      docker was the fucker that messed everything up and made me lose a few hours!\n
      \n
      EDIT 4:\n
      \n
      it seems that `ip route flush 0/0` restores the internet connectivity until reboot… I don’t know what does this means but can be a temporary workaround I guess? I really have no idea how to solve this\n
      \n
      FINAL EDIT: I gave up. I removed debian and installed fedora, and now it all works like a charm

      This is kind of a nutty network config. It looks like docker is setting up extra default routes, which I could easily see fouling everything up. As a first experiment (warning, this may ruin your networking until the next reboot):\n
      \n
      ```\n
      ip route flush 0/0\n
      ip route add default via 192.168.1.1 dev enp1s0\n
      \n
      ```\n
      \n
      ... and see if that makes things work (start with `ping 192.168.1.1` and `ping 8.8.8.8`). If that solves the problem, then I think something about your docker config is adding stuff to your networking that's causing the problem; maybe remove/disable docker completely and then re-add docker things one at a time to see where the problem comes in.

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n

    +url: null
    +body: """
      Hello! I (tried, at least) converted an old laptop to a Debian home server, and I was trying to set up duckdns.org and to enable port forwarding on my router. internet connection was working, I installed packages, docker, immich, etc, and then suddenly (I don’t know exactly when) it refuses to connect to the internet. It does connect to local addresses (I can ssh into it) but `ping google.com` and any other internet-involving command fail. I had set up a rule on the router to forward port 80 to the device’s port 80, but I then removed the rule and it still does not connect to the internet. I rebooted the router but nothing changed. Any idea what could be? the router is a Vodafone router.\n
      \n
      ![](https://lemmy.kde.social/pictrs/image/12682af4-71fe-4f72-bd99-82e613fbf507.png)\n
      \n
      I changed the hostname to debianserver but on the router it is still written debian. Also, it’s the only device with unknown ipv6\n
      \n
      thanks in advance!\n
      \n
      EDIT: I rebooted again the server, and now ipv6 is not unknown anymore, and the hostname is correct. however, it still does not connect to the internet\n
      \n
      ![](https://lemmy.kde.social/pictrs/image/b93cd90b-46ba-43d3-89e3-a5d02c0f1e07.png)\n
      \n
      EDIT 2:\n
      \n
      only one device (debianserver) has this problem, other devices work as before\n
      \n
      EDIT 3:\n
      \n
      I don’t know if it’s useful or not, but if I boot a live debian USB in the server internet works\n
      \n
      SOLUTION: aaaaand no it does not work, after restarting docker it seems to work because all the brodges are yet to be created and it takes some time, after like 30 seconds it does not work as before :(\n
      \n
      - edit the file `/lib/systemd/system/docker.service`\n
      - append the flag `–bip=192.168.3.1/24` to `ExecStart=…`\n
      - `systemctl daemon-reload`\n
      - `systemctl restart docker`\n
      \n
      docker was the fucker that messed everything up and made me lose a few hours!\n
      \n
      EDIT 4:\n
      \n
      it seems that `ip route flush 0/0` restores the internet connectivity until reboot… I don’t know what does this means but can be a temporary workaround I guess? I really have no idea how to solve this\n
      \n
      FINAL EDIT: I gave up. I removed debian and installed fedora, and now it all works like a charm

      This is kind of a nutty network config. It looks like docker is setting up extra default routes, which I could easily see fouling everything up. As a first experiment (warning, this may ruin your networking until the next reboot):\n
      \n
      ```\n
      ip route flush 0/0\n
      ip route add default via 192.168.1.1 dev enp1s0\n

      \n
      ... and see if that makes things work (start with `ping 192.168.1.1` and `ping 8.8.8.8`). If that solves the problem, then I think something about your docker config is adding stuff to your networking that's causing the problem; maybe remove/disable docker completely and then re-add docker things one at a time to see where the problem comes in.

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n

    +url: null
    +body: """
      Hello! I (tried, at least) converted an old laptop to a Debian home server, and I was trying to set up duckdns.org and to enable port forwarding on my router. internet connection was working, I installed packages, docker, immich, etc, and then suddenly (I don’t know exactly when) it refuses to connect to the internet. It does connect to local addresses (I can ssh into it) but `ping google.com` and any other internet-involving command fail. I had set up a rule on the router to forward port 80 to the device’s port 80, but I then removed the rule and it still does not connect to the internet. I rebooted the router but nothing changed. Any idea what could be? the router is a Vodafone router.\n
      \n
      ![](https://lemmy.kde.social/pictrs/image/12682af4-71fe-4f72-bd99-82e613fbf507.png)\n
      \n
      I changed the hostname to debianserver but on the router it is still written debian. Also, it’s the only device with unknown ipv6\n
      \n
      thanks in advance!\n
      \n
      EDIT: I rebooted again the server, and now ipv6 is not unknown anymore, and the hostname is correct. however, it still does not connect to the internet\n
      \n
      ![](https://lemmy.kde.social/pictrs/image/b93cd90b-46ba-43d3-89e3-a5d02c0f1e07.png)\n
      \n
      EDIT 2:\n
      \n
      only one device (debianserver) has this problem, other devices work as before\n
      \n
      EDIT 3:\n
      \n
      I don’t know if it’s useful or not, but if I boot a live debian USB in the server internet works\n
      \n
      SOLUTION: aaaaand no it does not work, after restarting docker it seems to work because all the brodges are yet to be created and it takes some time, after like 30 seconds it does not work as before :(\n
      \n
      - edit the file `/lib/systemd/system/docker.service`\n
      - append the flag `–bip=192.168.3.1/24` to `ExecStart=…`\n
      - `systemctl daemon-reload`\n
      - `systemctl restart docker`\n
      \n
      docker was the fucker that messed everything up and made me lose a few hours!\n
      \n
      EDIT 4:\n
      \n
      it seems that `ip route flush 0/0` restores the internet connectivity until reboot… I don’t know what does this means but can be a temporary workaround I guess? I really have no idea how to solve this\n
      \n
      FINAL EDIT: I gave up. I removed debian and installed fedora, and now it all works like a charm

      This is kind of a nutty network config. It looks like docker is setting up extra default routes, which I could easily see fouling everything up. As a first experiment (warning, this may ruin your networking until the next reboot):\n
      \n
      ```\n
      ip route flush 0/0\n
      ip route add default via 192.168.1.1 dev enp1s0\n

      ... and see if that makes things work (start with `ping 192.168.1.1` and `ping 8.8.8.8`). If that solves the problem, then I think something about your docker config is adding stuff to your networking that's causing the problem; maybe remove/disable docker completely and then re-add docker things one at a time to see where the problem comes in.

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n

    +title: "[not solved] I think I messed something up in the router settings but cannot understand what... now I have no internet connection"
    +url: null
    +body: """
      Hello! I (tried, at least) converted an old laptop to a Debian home server, and I was trying to set up duckdns.org and to enable port forwarding on my router. internet connection was working, I installed packages, docker, immich, etc, and then suddenly (I don’t know exactly when) it refuses to connect to the internet. It does connect to local addresses (I can ssh into it) but `ping google.com` and any other internet-involving command fail. I had set up a rule on the router to forward port 80 to the device’s port 80, but I then removed the rule and it still does not connect to the internet. I rebooted the router but nothing changed. Any idea what could be? the router is a Vodafone router.\n
      \n
      ![](https://lemmy.kde.social/pictrs/image/12682af4-71fe-4f72-bd99-82e613fbf507.png)\n
      \n
      I changed the hostname to debianserver but on the router it is still written debian. Also, it’s the only device with unknown ipv6\n
      \n
      thanks in advance!\n
      \n
      EDIT: I rebooted again the server, and now ipv6 is not unknown anymore, and the hostname is correct. however, it still does not connect to the internet\n
      \n
      ![](https://lemmy.kde.social/pictrs/image/b93cd90b-46ba-43d3-89e3-a5d02c0f1e07.png)\n
      \n
      EDIT 2:\n
      \n
      only one device (debianserver) has this problem, other devices work as before\n
      \n
      EDIT 3:\n
      \n
      I don’t know if it’s useful or not, but if I boot a live debian USB in the server internet works\n
      \n
      SOLUTION: aaaaand no it does not work, after restarting docker it seems to work because all the brodges are yet to be created and it takes some time, after like 30 seconds it does not work as before :(\n
      \n
      - edit the file `/lib/systemd/system/docker.service`\n
      - append the flag `–bip=192.168.3.1/24` to `ExecStart=…`\n
      - `systemctl daemon-reload`\n
      - `systemctl restart docker`\n
      \n
      docker was the fucker that messed everything up and made me lose a few hours!\n
      \n
      EDIT 4:\n
      \n
      it seems that `ip route flush 0/0` restores the internet connectivity until reboot… I don’t know what does this means but can be a temporary workaround I guess? I really have no idea how to solve this\n
      \n
      FINAL EDIT: I gave up. I removed debian and installed fedora, and now it all works like a charm

        This is kind of a nutty network config. It looks like docker is setting up extra default routes, which I could easily see fouling everything up. As a first experiment (warning, this may ruin your networking until the next reboot):\n
        \n
        ```\n
        ip route flush 0/0\n
        ip route add default via 192.168.1.1 dev enp1s0\n
        \n
        ```\n
        \n
        ... and see if that makes things work (start with `ping 192.168.1.1` and `ping 8.8.8.8`). If that solves the problem, then I think something about your docker config is adding stuff to your networking that's causing the problem; maybe remove/disable docker completely and then re-add docker things one at a time to see where the problem comes in.

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n

    +url: null
    +body: """
      Hello! I (tried, at least) converted an old laptop to a Debian home server, and I was trying to set up duckdns.org and to enable port forwarding on my router. internet connection was working, I installed packages, docker, immich, etc, and then suddenly (I don’t know exactly when) it refuses to connect to the internet. It does connect to local addresses (I can ssh into it) but `ping google.com` and any other internet-involving command fail. I had set up a rule on the router to forward port 80 to the device’s port 80, but I then removed the rule and it still does not connect to the internet. I rebooted the router but nothing changed. Any idea what could be? the router is a Vodafone router.\n
      \n
      ![](https://lemmy.kde.social/pictrs/image/12682af4-71fe-4f72-bd99-82e613fbf507.png)\n
      \n
      I changed the hostname to debianserver but on the router it is still written debian. Also, it’s the only device with unknown ipv6\n
      \n
      thanks in advance!\n
      \n
      EDIT: I rebooted again the server, and now ipv6 is not unknown anymore, and the hostname is correct. however, it still does not connect to the internet\n
      \n
      ![](https://lemmy.kde.social/pictrs/image/b93cd90b-46ba-43d3-89e3-a5d02c0f1e07.png)\n
      \n
      EDIT 2:\n
      \n
      only one device (debianserver) has this problem, other devices work as before\n
      \n
      EDIT 3:\n
      \n
      I don’t know if it’s useful or not, but if I boot a live debian USB in the server internet works\n
      \n
      SOLUTION: aaaaand no it does not work, after restarting docker it seems to work because all the brodges are yet to be created and it takes some time, after like 30 seconds it does not work as before :(\n
      \n
      - edit the file `/lib/systemd/system/docker.service`\n
      - append the flag `–bip=192.168.3.1/24` to `ExecStart=…`\n
      - `systemctl daemon-reload`\n
      - `systemctl restart docker`\n
      \n
      docker was the fucker that messed everything up and made me lose a few hours!\n
      \n
      EDIT 4:\n
      \n
      it seems that `ip route flush 0/0` restores the internet connectivity until reboot… I don’t know what does this means but can be a temporary workaround I guess? I really have no idea how to solve this\n
      \n
      FINAL EDIT: I gave up. I removed debian and installed fedora, and now it all works like a charm

        This is kind of a nutty network config. It looks like docker is setting up extra default routes, which I could easily see fouling everything up. As a first experiment (warning, this may ruin your networking until the next reboot):\n
        \n
        ```\n
        ip route flush 0/0\n
        ip route add default via 192.168.1.1 dev enp1s0\n

        ... and see if that makes things work (start with `ping 192.168.1.1` and `ping 8.8.8.8`). If that solves the problem, then I think something about your docker config is adding stuff to your networking that's causing the problem; maybe remove/disable docker completely and then re-add docker things one at a time to see where the problem comes in.

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n

      Hello! I (tried, at least) converted an old laptop to a Debian home server, and I was trying to set up duckdns.org and to enable port forwarding on my router. internet connection was working, I installed packages, docker, immich, etc, and then suddenly (I don’t know exactly when) it refuses to connect to the internet. It does connect to local addresses (I can ssh into it) but `ping google.com` and any other internet-involving command fail. I had set up a rule on the router to forward port 80 to the device’s port 80, but I then removed the rule and it still does not connect to the internet. I rebooted the router but nothing changed. Any idea what could be? the router is a Vodafone router.\n

      I changed the hostname to debianserver but on the router it is still written debian. Also, it’s the only device with unknown ipv6\n
      \n
      thanks in advance!\n
      \n
      EDIT: I rebooted again the server, and now ipv6 is not unknown anymore, and the hostname is correct. however, it still does not connect to the internet\n

      \n
      EDIT 2:\n
      \n
      only one device (debianserver) has this problem, other devices work as before\n
      \n
      EDIT 3:\n
      \n
      I don’t know if it’s useful or not, but if I boot a live debian USB in the server internet works\n
      \n
      SOLUTION: aaaaand no it does not work, after restarting docker it seems to work because all the brodges are yet to be created and it takes some time, after like 30 seconds it does not work as before :(\n
      \n
      - edit the file `/lib/systemd/system/docker.service`\n
      - append the flag `–bip=192.168.3.1/24` to `ExecStart=…`\n
      - `systemctl daemon-reload`\n
      - `systemctl restart docker`\n
      \n
      docker was the fucker that messed everything up and made me lose a few hours!\n
      \n
      EDIT 4:\n
      \n
      it seems that `ip route flush 0/0` restores the internet connectivity until reboot… I don’t know what does this means but can be a temporary workaround I guess? I really have no idea how to solve this\n
      \n
      FINAL EDIT: I gave up. I removed debian and installed fedora, and now it all works like a charm

        This is kind of a nutty network config. It looks like docker is setting up extra default routes, which I could easily see fouling everything up. As a first experiment (warning, this may ruin your networking until the next reboot):\n

        ```\n
        ip route flush 0/0\n

If that solves the problem, then I think something about your docker config is adding stuff to your networking that's causing the problem; maybe remove/disable docker completely and then re-add docker things one at a time to see where the problem comes in.

    What does `docker network inspect [network]` say for each of your Docker networks (substituting each Docker network for "[network]")? What's the network section of `docker-compose.yml` look like?

        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n

        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n

    +url: null
    +body: """
      Hello! I (tried, at least) converted an old laptop to a Debian home server, and I was trying to set up duckdns.org and to enable port forwarding on my router. internet connection was working, I installed packages, docker, immich, etc, and then suddenly (I don’t know exactly when) it refuses to connect to the internet. It does connect to local addresses (I can ssh into it) but `ping google.com` and any other internet-involving command fail. I had set up a rule on the router to forward port 80 to the device’s port 80, but I then removed the rule and it still does not connect to the internet. I rebooted the router but nothing changed. Any idea what could be? the router is a Vodafone router.\n
      \n
      ![](https://lemmy.kde.social/pictrs/image/12682af4-71fe-4f72-bd99-82e613fbf507.png)\n
      \n
      I changed the hostname to debianserver but on the router it is still written debian. Also, it’s the only device with unknown ipv6\n
      \n
      thanks in advance!\n
      \n
      EDIT: I rebooted again the server, and now ipv6 is not unknown anymore, and the hostname is correct. however, it still does not connect to the internet\n
      \n
      ![](https://lemmy.kde.social/pictrs/image/b93cd90b-46ba-43d3-89e3-a5d02c0f1e07.png)\n
      \n
      EDIT 2:\n
      \n
      only one device (debianserver) has this problem, other devices work as before\n
      \n
      EDIT 3:\n
      \n
      I don’t know if it’s useful or not, but if I boot a live debian USB in the server internet works\n
      \n
      SOLUTION: aaaaand no it does not work, after restarting docker it seems to work because all the brodges are yet to be created and it takes some time, after like 30 seconds it does not work as before :(\n
      \n
      - edit the file `/lib/systemd/system/docker.service`\n
      - append the flag `–bip=192.168.3.1/24` to `ExecStart=…`\n
      - `systemctl daemon-reload`\n
      - `systemctl restart docker`\n
      \n
      docker was the fucker that messed everything up and made me lose a few hours!\n
      \n
      EDIT 4:\n
      \n
      it seems that `ip route flush 0/0` restores the internet connectivity until reboot… I don’t know what does this means but can be a temporary workaround I guess? I really have no idea how to solve this\n
      \n
      FINAL EDIT: I gave up. I removed debian and installed fedora, and now it all works like a charm

    +body: """
      Hello! I (tried, at least) converted an old laptop to a Debian home server, and I was trying to set up duckdns.org and to enable port forwarding on my router. internet connection was working, I installed packages, docker, immich, etc, and then suddenly (I don’t know exactly when) it refuses to connect to the internet. It does connect to local addresses (I can ssh into it) but `ping google.com` and any other internet-involving command fail. I had set up a rule on the router to forward port 80 to the device’s port 80, but I then removed the rule and it still does not connect to the internet. I rebooted the router but nothing changed. Any idea what could be? the router is a Vodafone router.\n

      \n
      I changed the hostname to debianserver but on the router it is still written debian. Also, it’s the only device with unknown ipv6\n
      \n
      thanks in advance!\n
      \n
      EDIT: I rebooted again the server, and now ipv6 is not unknown anymore, and the hostname is correct. however, it still does not connect to the internet\n
      \n
      ![](https://lemmy.kde.social/pictrs/image/b93cd90b-46ba-43d3-89e3-a5d02c0f1e07.png)\n
      \n
      EDIT 2:\n
      \n
      only one device (debianserver) has this problem, other devices work as before\n
      \n
      EDIT 3:\n
      \n
      I don’t know if it’s useful or not, but if I boot a live debian USB in the server internet works\n
      \n
      SOLUTION: aaaaand no it does not work, after restarting docker it seems to work because all the brodges are yet to be created and it takes some time, after like 30 seconds it does not work as before :(\n
      \n
      - edit the file `/lib/systemd/system/docker.service`\n
      - append the flag `–bip=192.168.3.1/24` to `ExecStart=…`\n
      - `systemctl daemon-reload`\n
      - `systemctl restart docker`\n
      \n
      docker was the fucker that messed everything up and made me lose a few hours!\n
      \n
      EDIT 4:\n
      \n
      it seems that `ip route flush 0/0` restores the internet connectivity until reboot… I don’t know what does this means but can be a temporary workaround I guess? I really have no idea how to solve this\n
      \n
      FINAL EDIT: I gave up. I removed debian and installed fedora, and now it all works like a charm

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n

    +body: """
      Hello! I (tried, at least) converted an old laptop to a Debian home server, and I was trying to set up duckdns.org and to enable port forwarding on my router. internet connection was working, I installed packages, docker, immich, etc, and then suddenly (I don’t know exactly when) it refuses to connect to the internet. It does connect to local addresses (I can ssh into it) but `ping google.com` and any other internet-involving command fail. I had set up a rule on the router to forward port 80 to the device’s port 80, but I then removed the rule and it still does not connect to the internet. I rebooted the router but nothing changed. Any idea what could be? the router is a Vodafone router.\n
      \n
      ![](https://lemmy.kde.social/pictrs/image/12682af4-71fe-4f72-bd99-82e613fbf507.png)\n
      \n
      I changed the hostname to debianserver but on the router it is still written debian. Also, it’s the only device with unknown ipv6\n
      \n
      thanks in advance!\n
      \n
      EDIT: I rebooted again the server, and now ipv6 is not unknown anymore, and the hostname is correct. however, it still does not connect to the internet\n
      \n
      ![](https://lemmy.kde.social/pictrs/image/b93cd90b-46ba-43d3-89e3-a5d02c0f1e07.png)\n
      \n
      EDIT 2:\n
      \n
      only one device (debianserver) has this problem, other devices work as before\n
      \n
      EDIT 3:\n
      \n
      I don’t know if it’s useful or not, but if I boot a live debian USB in the server internet works\n
      \n
      SOLUTION: aaaaand no it does not work, after restarting docker it seems to work because all the brodges are yet to be created and it takes some time, after like 30 seconds it does not work as before :(\n
      \n
      - edit the file `/lib/systemd/system/docker.service`\n
      - append the flag `–bip=192.168.3.1/24` to `ExecStart=…`\n
      - `systemctl daemon-reload`\n
      - `systemctl restart docker`\n
      \n
      docker was the fucker that messed everything up and made me lose a few hours!\n
      \n
      EDIT 4:\n
      \n
      it seems that `ip route flush 0/0` restores the internet connectivity until reboot… I don’t know what does this means but can be a temporary workaround I guess? I really have no idea how to solve this\n
      \n
      FINAL EDIT: I gave up. I removed debian and installed fedora, and now it all works like a charm

I had set up a rule on the router to forward port 80 to the device’s port 80, but I then removed the rule and it still does not connect to the internet. I rebooted the router but nothing changed. Any idea what could be? the router is a Vodafone router.\n

      \n
      I changed the hostname to debianserver but on the router it is still written debian. Also, it’s the only device with unknown ipv6\n
      \n
      thanks in advance!\n
      \n
      EDIT: I rebooted again the server, and now ipv6 is not unknown anymore, and the hostname is correct. however, it still does not connect to the internet\n

      \n
      EDIT 2:\n
      \n
      only one device (debianserver) has this problem, other devices work as before\n
      \n
      EDIT 3:\n
      \n
      I don’t know if it’s useful or not, but if I boot a live debian USB in the server internet works\n
      \n
      SOLUTION: aaaaand no it does not work, after restarting docker it seems to work because all the brodges are yet to be created and it takes some time, after like 30 seconds it does not work as before :(\n
      \n
      - edit the file `/lib/systemd/system/docker.service`\n
      - append the flag `–bip=192.168.3.1/24` to `ExecStart=…`\n
      - `systemctl daemon-reload`\n
      - `systemctl restart docker`\n
      \n
      docker was the fucker that messed everything up and made me lose a few hours!\n
      \n
      EDIT 4:\n
      \n
      it seems that `ip route flush 0/0` restores the internet connectivity until reboot… I don’t know what does this means but can be a temporary workaround I guess? I really have no idea how to solve this\n
      \n
      FINAL EDIT: I gave up. I removed debian and installed fedora, and now it all works like a charm

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n

    +title: "[not solved] I think I messed something up in the router settings but cannot understand what... now I have no internet connection"
    +url: null
    +body: """
      Hello! I (tried, at least) converted an old laptop to a Debian home server, and I was trying to set up duckdns.org and to enable port forwarding on my router. internet connection was working, I installed packages, docker, immich, etc, and then suddenly (I don’t know exactly when) it refuses to connect to the internet. It does connect to local addresses (I can ssh into it) but `ping google.com` and any other internet-involving command fail. I had set up a rule on the router to forward port 80 to the device’s port 80, but I then removed the rule and it still does not connect to the internet. I rebooted the router but nothing changed. Any idea what could be? the router is a Vodafone router.\n
      \n
      ![](https://lemmy.kde.social/pictrs/image/12682af4-71fe-4f72-bd99-82e613fbf507.png)\n
      \n
      I changed the hostname to debianserver but on the router it is still written debian. Also, it’s the only device with unknown ipv6\n
      \n
      thanks in advance!\n
      \n
      EDIT: I rebooted again the server, and now ipv6 is not unknown anymore, and the hostname is correct. however, it still does not connect to the internet\n
      \n
      ![](https://lemmy.kde.social/pictrs/image/b93cd90b-46ba-43d3-89e3-a5d02c0f1e07.png)\n
      \n
      EDIT 2:\n
      \n
      only one device (debianserver) has this problem, other devices work as before\n
      \n
      EDIT 3:\n
      \n
      I don’t know if it’s useful or not, but if I boot a live debian USB in the server internet works\n
      \n
      SOLUTION: aaaaand no it does not work, after restarting docker it seems to work because all the brodges are yet to be created and it takes some time, after like 30 seconds it does not work as before :(\n
      \n
      - edit the file `/lib/systemd/system/docker.service`\n
      - append the flag `–bip=192.168.3.1/24` to `ExecStart=…`\n
      - `systemctl daemon-reload`\n
      - `systemctl restart docker`\n
      \n
      docker was the fucker that messed everything up and made me lose a few hours!\n
      \n
      EDIT 4:\n
      \n
      it seems that `ip route flush 0/0` restores the internet connectivity until reboot… I don’t know what does this means but can be a temporary workaround I guess? I really have no idea how to solve this\n
      \n
      FINAL EDIT: I gave up. I removed debian and installed fedora, and now it all works like a charm

    If it shows as working, then you can narrow it down to incorrect DNS and IP routing. Perhaps dynamic IP allocation is set to off or another configuration error or bug, in which case you might need to reset all the router settings. Then, is it only broken for a single end device?

        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
        \n
        ### Rules\n
        \n
        - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
        - No misinformation\n
        - No NSFW content\n
        - No hate speech, bigotry, etc\n

      Hello! I (tried, at least) converted an old laptop to a Debian home server, and I was trying to set up duckdns.org and to enable port forwarding on my router. internet connection was working, I installed packages, docker, immich, etc, and then suddenly (I don’t know exactly when) it refuses to connect to the internet. It does connect to local addresses (I can ssh into it) but `ping google.com` and any other internet-involving command fail. I had set up a rule on the router to forward port 80 to the device’s port 80, but I then removed the rule and it still does not connect to the internet. I rebooted the router but nothing changed. Any idea what could be? the router is a Vodafone router.\n

      I changed the hostname to debianserver but on the router it is still written debian. Also, it’s the only device with unknown ipv6\n
      \n
      thanks in advance!\n
      \n
      EDIT: I rebooted again the server, and now ipv6 is not unknown anymore, and the hostname is correct. however, it still does not connect to the internet\n

      \n
      EDIT 2:\n
      \n
      only one device (debianserver) has this problem, other devices work as before\n
      \n
      EDIT 3:\n
      \n
      I don’t know if it’s useful or not, but if I boot a live debian USB in the server internet works\n
      \n
      SOLUTION: aaaaand no it does not work, after restarting docker it seems to work because all the brodges are yet to be created and it takes some time, after like 30 seconds it does not work as before :(\n
      \n
      - edit the file `/lib/systemd/system/docker.service`\n
      - append the flag `–bip=192.168.3.1/24` to `ExecStart=…`\n
      - `systemctl daemon-reload`\n
      - `systemctl restart docker`\n
      \n
      docker was the fucker that messed everything up and made me lose a few hours!\n
      \n
      EDIT 4:\n
      \n
      it seems that `ip route flush 0/0` restores the internet connectivity until reboot… I don’t know what does this means but can be a temporary workaround I guess? I really have no idea how to solve this\n
      \n
      FINAL EDIT: I gave up. I removed debian and installed fedora, and now it all works like a charm

    Go to the outer status page. The router should display whether it has an internet connection to your provider. If no, then your router/modem has no credentials or another issue preventing access.\n
    \n
    If it shows as working, then you can narrow it down to incorrect DNS and IP routing. Perhaps dynamic IP allocation is set to off or another configuration error or bug, in which case you might need to reset all the router settings. Then, is it only broken for a single end device?

        From Wikipedia, the free encyclopedia\n
        \n
        Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
        \n
        Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n

    +url: null
    +body: """
      Hello! I (tried, at least) converted an old laptop to a Debian home server, and I was trying to set up duckdns.org and to enable port forwarding on my router. internet connection was working, I installed packages, docker, immich, etc, and then suddenly (I don’t know exactly when) it refuses to connect to the internet. It does connect to local addresses (I can ssh into it) but `ping google.com` and any other internet-involving command fail. I had set up a rule on the router to forward port 80 to the device’s port 80, but I then removed the rule and it still does not connect to the internet. I rebooted the router but nothing changed. Any idea what could be? the router is a Vodafone router.\n
      \n
      ![](https://lemmy.kde.social/pictrs/image/12682af4-71fe-4f72-bd99-82e613fbf507.png)\n
      \n
      I changed the hostname to debianserver but on the router it is still written debian. Also, it’s the only device with unknown ipv6\n
      \n
      thanks in advance!\n
      \n
      EDIT: I rebooted again the server, and now ipv6 is not unknown anymore, and the hostname is correct. however, it still does not connect to the internet\n
      \n
      ![](https://lemmy.kde.social/pictrs/image/b93cd90b-46ba-43d3-89e3-a5d02c0f1e07.png)\n
      \n
      EDIT 2:\n
      \n
      only one device (debianserver) has this problem, other devices work as before\n
      \n
      EDIT 3:\n
      \n
      I don’t know if it’s useful or not, but if I boot a live debian USB in the server internet works\n
      \n
      SOLUTION: aaaaand no it does not work, after restarting docker it seems to work because all the brodges are yet to be created and it takes some time, after like 30 seconds it does not work as before :(\n
      \n
      - edit the file `/lib/systemd/system/docker.service`\n
      - append the flag `–bip=192.168.3.1/24` to `ExecStart=…`\n
      - `systemctl daemon-reload`\n
      - `systemctl restart docker`\n
      \n
      docker was the fucker that messed everything up and made me lose a few hours!\n
      \n
      EDIT 4:\n
      \n
      it seems that `ip route flush 0/0` restores the internet connectivity until reboot… I don’t know what does this means but can be a temporary workaround I guess? I really have no idea how to solve this\n
      \n
      FINAL EDIT: I gave up. I removed debian and installed fedora, and now it all works like a charm

      Hello! I (tried, at least) converted an old laptop to a Debian home server, and I was trying to set up duckdns.org and to enable port forwarding on my router. internet connection was working, I installed packages, docker, immich, etc, and then suddenly (I don’t know exactly when) it refuses to connect to the internet. It does connect to local addresses (I can ssh into it) but `ping google.com` and any other internet-involving command fail. I had set up a rule on the router to forward port 80 to the device’s port 80, but I then removed the rule and it still does not connect to the internet. I rebooted the router but nothing changed. Any idea what could be? the router is a Vodafone router.\n
      \n
      ![](https://lemmy.kde.social/pictrs/image/12682af4-71fe-4f72-bd99-82e613fbf507.png)\n
      \n
      I changed the hostname to debianserver but on the router it is still written debian. Also, it’s the only device with unknown ipv6\n
      \n
      thanks in advance!\n
      \n
      EDIT: I rebooted again the server, and now ipv6 is not unknown anymore, and the hostname is correct. however, it still does not connect to the internet\n
      \n
      ![](https://lemmy.kde.social/pictrs/image/b93cd90b-46ba-43d3-89e3-a5d02c0f1e07.png)\n
      \n
      EDIT 2:\n
      \n
      only one device (debianserver) has this problem, other devices work as before\n
      \n
      EDIT 3:\n
      \n
      I don’t know if it’s useful or not, but if I boot a live debian USB in the server internet works\n
      \n
      SOLUTION: aaaaand no it does not work, after restarting docker it seems to work because all the brodges are yet to be created and it takes some time, after like 30 seconds it does not work as before :(\n
      \n
      - edit the file `/lib/systemd/system/docker.service`\n
      - append the flag `–bip=192.168.3.1/24` to `ExecStart=…`\n
      - `systemctl daemon-reload`\n
      - `systemctl restart docker`\n
      \n
      docker was the fucker that messed everything up and made me lose a few hours!\n
      \n
      EDIT 4:\n
      \n
      it seems that `ip route flush 0/0` restores the internet connectivity until reboot… I don’t know what does this means but can be a temporary workaround I guess? I really have no idea how to solve this\n
      \n
      FINAL EDIT: I gave up. I removed debian and installed fedora, and now it all works like a charm

      Go to the outer status page. The router should display whether it has an internet connection to your provider. If no, then your router/modem has no credentials or another issue preventing access.\n
      \n
      If it shows as working, then you can narrow it down to incorrect DNS and IP routing. Perhaps dynamic IP allocation is set to off or another configuration error or bug, in which case you might need to reset all the router settings. Then, is it only broken for a single end device?

I had set up a rule on the router to forward port 80 to the device’s port 80, but I then removed the rule and it still does not connect to the internet. I rebooted the router but nothing changed. Any idea what could be? the router is a Vodafone router.\n

      \n
      I changed the hostname to debianserver but on the router it is still written debian. Also, it’s the only device with unknown ipv6\n
      \n
      thanks in advance!\n
      \n
      EDIT: I rebooted again the server, and now ipv6 is not unknown anymore, and the hostname is correct. however, it still does not connect to the internet\n

      \n
      EDIT 2:\n
      \n
      only one device (debianserver) has this problem, other devices work as before\n
      \n
      EDIT 3:\n
      \n
      I don’t know if it’s useful or not, but if I boot a live debian USB in the server internet works\n
      \n
      SOLUTION: aaaaand no it does not work, after restarting docker it seems to work because all the brodges are yet to be created and it takes some time, after like 30 seconds it does not work as before :(\n
      \n
      - edit the file `/lib/systemd/system/docker.service`\n
      - append the flag `–bip=192.168.3.1/24` to `ExecStart=…`\n
      - `systemctl daemon-reload`\n
      - `systemctl restart docker`\n
      \n
      docker was the fucker that messed everything up and made me lose a few hours!\n
      \n
      EDIT 4:\n
      \n
      it seems that `ip route flush 0/0` restores the internet connectivity until reboot… I don’t know what does this means but can be a temporary workaround I guess? I really have no idea how to solve this\n
      \n
      FINAL EDIT: I gave up. I removed debian and installed fedora, and now it all works like a charm

      Go to the outer status page. The router should display whether it has an internet connection to your provider. If no, then your router/modem has no credentials or another issue preventing access.\n
      \n
      If it shows as working, then you can narrow it down to incorrect DNS and IP routing. Perhaps dynamic IP allocation is set to off or another configuration error or bug, in which case you might need to reset all the router settings. Then, is it only broken for a single end device?

    From Wikipedia, the free encyclopedia\n
    \n
    Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
    \n
    Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
    \n
