    +title: "Issues forwarding traffic through a wireguard connection"
    +url: null
    +body: """
      I am attempting to follow this [procustodibus.com/…/wireguard-port-forward-from-i…](https://www.procustodibus.com/blog/2022/09/wireguard-port-forward-from-internet) to forward traffic from a few ports on a public oracle vps to other ports on my local server through a wireguard connection. Currently I am doing this using rinetd, but I was looking for a more normal way of forwarding traffic. (Also looking to forward UDP traffic at some point.)\n
      \n
      After stopping rinetd, adding these rules to the public server’s wg config\n
      \n
      ```\n
      \n
      <span style="color:#323232;"># packet forwarding\n
      </span><span style="color:#323232;">PreUp = sysctl -w net.ipv4.ip_forward=1\n
      </span><span style="color:#323232;">\n
      </span><span style="color:#323232;"># port forwarding\n
      </span><span style="color:#323232;">PreUp = iptables -t nat -A PREROUTING -i ens3 -p tcp --dport 443 -j DNAT --to-destination 10.144.65.2:8443\n
      </span><span style="color:#323232;">PostDown = iptables -t nat -D PREROUTING -i ens3 -p tcp --dport 443 -j DNAT --to-destination 10.144.65.2:8443\n
      </span><span style="color:#323232;">\n
      </span><span style="color:#323232;"># packet masquerading\n
      </span><span style="color:#323232;">PreUp = iptables -t nat -A POSTROUTING -o wg0 -j MASQUERADE\n
      </span><span style="color:#323232;">PostDown = iptables -t nat -D POSTROUTING -o wg0 -j MASQUERADE\n
      </span>\n
      ```\n
      \n
      and restarting the wg connection, I’m seeing traffic on the ens3 port but none entering wg0 via tcpdump. I feel like I probably have conflicting iptables rules saved [pastebin.com/0eNwhNKM](https://pastebin.com/0eNwhNKM) but I don’t really know enough about whats going on there to fix it. I feel like its probably the wireguard-*-rule ones (created by pivpn possibly?) but I’m not sure.\n
      \n
      Edit way later: Ended up just using rinetd for the udp connections. Ubuntu doesn’t include the latest version here [github.com/samhocevar/rinetd](https://github.com/samhocevar/rinetd) which *is* able to do UDP connections. The docker container RxBrad suggested uses that version within the docker container to make the redirections so it will be roughly equivalent.

    +title: "Issues forwarding traffic through a wireguard connection"
    +url: null
    +body: """
      I am attempting to follow this [procustodibus.com/…/wireguard-port-forward-from-i…](https://www.procustodibus.com/blog/2022/09/wireguard-port-forward-from-internet) to forward traffic from a few ports on a public oracle vps to other ports on my local server through a wireguard connection. Currently I am doing this using rinetd, but I was looking for a more normal way of forwarding traffic. (Also looking to forward UDP traffic at some point.)\n
      \n
      After stopping rinetd, adding these rules to the public server’s wg config\n
      \n
      ```\n
      \n
      <span style="color:#323232;"># packet forwarding\n
      </span><span style="color:#323232;">PreUp = sysctl -w net.ipv4.ip_forward=1\n
      </span><span style="color:#323232;">\n
      </span><span style="color:#323232;"># port forwarding\n
      </span><span style="color:#323232;">PreUp = iptables -t nat -A PREROUTING -i ens3 -p tcp --dport 443 -j DNAT --to-destination 10.144.65.2:8443\n
      </span><span style="color:#323232;">PostDown = iptables -t nat -D PREROUTING -i ens3 -p tcp --dport 443 -j DNAT --to-destination 10.144.65.2:8443\n
      </span><span style="color:#323232;">\n
      </span><span style="color:#323232;"># packet masquerading\n
      </span><span style="color:#323232;">PreUp = iptables -t nat -A POSTROUTING -o wg0 -j MASQUERADE\n
      </span><span style="color:#323232;">PostDown = iptables -t nat -D POSTROUTING -o wg0 -j MASQUERADE\n
      </span>\n
      ```\n
      \n
      and restarting the wg connection, I’m seeing traffic on the ens3 port but none entering wg0 via tcpdump. I feel like I probably have conflicting iptables rules saved [pastebin.com/0eNwhNKM](https://pastebin.com/0eNwhNKM) but I don’t really know enough about whats going on there to fix it. I feel like its probably the wireguard-*-rule ones (created by pivpn possibly?) but I’m not sure.\n
      \n
      Edit way later: Ended up just using rinetd for the udp connections. Ubuntu doesn’t include the latest version here [github.com/samhocevar/rinetd](https://github.com/samhocevar/rinetd) which *is* able to do UDP connections. The docker container RxBrad suggested uses that version within the docker container to make the redirections so it will be roughly equivalent.

    +title: "Issues forwarding traffic through a wireguard connection"
    +url: null
    +body: """
      I am attempting to follow this [procustodibus.com/…/wireguard-port-forward-from-i…](https://www.procustodibus.com/blog/2022/09/wireguard-port-forward-from-internet) to forward traffic from a few ports on a public oracle vps to other ports on my local server through a wireguard connection. Currently I am doing this using rinetd, but I was looking for a more normal way of forwarding traffic. (Also looking to forward UDP traffic at some point.)\n
      \n
      After stopping rinetd, adding these rules to the public server’s wg config\n
      \n
      ```\n
      \n
      <span style="color:#323232;"># packet forwarding\n
      </span><span style="color:#323232;">PreUp = sysctl -w net.ipv4.ip_forward=1\n
      </span><span style="color:#323232;">\n
      </span><span style="color:#323232;"># port forwarding\n
      </span><span style="color:#323232;">PreUp = iptables -t nat -A PREROUTING -i ens3 -p tcp --dport 443 -j DNAT --to-destination 10.144.65.2:8443\n
      </span><span style="color:#323232;">PostDown = iptables -t nat -D PREROUTING -i ens3 -p tcp --dport 443 -j DNAT --to-destination 10.144.65.2:8443\n
      </span><span style="color:#323232;">\n
      </span><span style="color:#323232;"># packet masquerading\n
      </span><span style="color:#323232;">PreUp = iptables -t nat -A POSTROUTING -o wg0 -j MASQUERADE\n
      </span><span style="color:#323232;">PostDown = iptables -t nat -D POSTROUTING -o wg0 -j MASQUERADE\n
      </span>\n
      ```\n
      \n
      and restarting the wg connection, I’m seeing traffic on the ens3 port but none entering wg0 via tcpdump. I feel like I probably have conflicting iptables rules saved [pastebin.com/0eNwhNKM](https://pastebin.com/0eNwhNKM) but I don’t really know enough about whats going on there to fix it. I feel like its probably the wireguard-*-rule ones (created by pivpn possibly?) but I’m not sure.\n
      \n
      Edit way later: Ended up just using rinetd for the udp connections. Ubuntu doesn’t include the latest version here [github.com/samhocevar/rinetd](https://github.com/samhocevar/rinetd) which *is* able to do UDP connections. The docker container RxBrad suggested uses that version within the docker container to make the redirections so it will be roughly equivalent.

      I am attempting to follow this [procustodibus.com/…/wireguard-port-forward-from-i…](https://www.procustodibus.com/blog/2022/09/wireguard-port-forward-from-internet) to forward traffic from a few ports on a public oracle vps to other ports on my local server through a wireguard connection. Currently I am doing this using rinetd, but I was looking for a more normal way of forwarding traffic. (Also looking to forward UDP traffic at some point.)\n

      ```\n
      \n
      and restarting the wg connection, I’m seeing traffic on the ens3 port but none entering wg0 via tcpdump. I feel like I probably have conflicting iptables rules saved [pastebin.com/0eNwhNKM](https://pastebin.com/0eNwhNKM) but I don’t really know enough about whats going on there to fix it. I feel like its probably the wireguard-*-rule ones (created by pivpn possibly?) but I’m not sure.\n
      \n
      Edit way later: Ended up just using rinetd for the udp connections. Ubuntu doesn’t include the latest version here [github.com/samhocevar/rinetd](https://github.com/samhocevar/rinetd) which *is* able to do UDP connections. The docker container RxBrad suggested uses that version within the docker container to make the redirections so it will be roughly equivalent.

    +url: null
    +body: """
      I am attempting to follow this [procustodibus.com/…/wireguard-port-forward-from-i…](https://www.procustodibus.com/blog/2022/09/wireguard-port-forward-from-internet) to forward traffic from a few ports on a public oracle vps to other ports on my local server through a wireguard connection. Currently I am doing this using rinetd, but I was looking for a more normal way of forwarding traffic. (Also looking to forward UDP traffic at some point.)\n
      \n
      After stopping rinetd, adding these rules to the public server’s wg config\n
      \n
      ```\n
      \n
      <span style="color:#323232;"># packet forwarding\n
      </span><span style="color:#323232;">PreUp = sysctl -w net.ipv4.ip_forward=1\n
      </span><span style="color:#323232;">\n
      </span><span style="color:#323232;"># port forwarding\n
      </span><span style="color:#323232;">PreUp = iptables -t nat -A PREROUTING -i ens3 -p tcp --dport 443 -j DNAT --to-destination 10.144.65.2:8443\n
      </span><span style="color:#323232;">PostDown = iptables -t nat -D PREROUTING -i ens3 -p tcp --dport 443 -j DNAT --to-destination 10.144.65.2:8443\n
      </span><span style="color:#323232;">\n
      </span><span style="color:#323232;"># packet masquerading\n
      </span><span style="color:#323232;">PreUp = iptables -t nat -A POSTROUTING -o wg0 -j MASQUERADE\n
      </span><span style="color:#323232;">PostDown = iptables -t nat -D POSTROUTING -o wg0 -j MASQUERADE\n
      </span>\n
      ```\n
      \n
      and restarting the wg connection, I’m seeing traffic on the ens3 port but none entering wg0 via tcpdump. I feel like I probably have conflicting iptables rules saved [pastebin.com/0eNwhNKM](https://pastebin.com/0eNwhNKM) but I don’t really know enough about whats going on there to fix it. I feel like its probably the wireguard-*-rule ones (created by pivpn possibly?) but I’m not sure.\n
      \n
      Edit way later: Ended up just using rinetd for the udp connections. Ubuntu doesn’t include the latest version here [github.com/samhocevar/rinetd](https://github.com/samhocevar/rinetd) which *is* able to do UDP connections. The docker container RxBrad suggested uses that version within the docker container to make the redirections so it will be roughly equivalent.

    +title: "Issues forwarding traffic through a wireguard connection"
    +url: null
    +body: """
      I am attempting to follow this [procustodibus.com/…/wireguard-port-forward-from-i…](https://www.procustodibus.com/blog/2022/09/wireguard-port-forward-from-internet) to forward traffic from a few ports on a public oracle vps to other ports on my local server through a wireguard connection. Currently I am doing this using rinetd, but I was looking for a more normal way of forwarding traffic. (Also looking to forward UDP traffic at some point.)\n
      \n
      After stopping rinetd, adding these rules to the public server’s wg config\n
      \n
      ```\n
      \n
      <span style="color:#323232;"># packet forwarding\n
      </span><span style="color:#323232;">PreUp = sysctl -w net.ipv4.ip_forward=1\n
      </span><span style="color:#323232;">\n
      </span><span style="color:#323232;"># port forwarding\n
      </span><span style="color:#323232;">PreUp = iptables -t nat -A PREROUTING -i ens3 -p tcp --dport 443 -j DNAT --to-destination 10.144.65.2:8443\n
      </span><span style="color:#323232;">PostDown = iptables -t nat -D PREROUTING -i ens3 -p tcp --dport 443 -j DNAT --to-destination 10.144.65.2:8443\n
      </span><span style="color:#323232;">\n
      </span><span style="color:#323232;"># packet masquerading\n
      </span><span style="color:#323232;">PreUp = iptables -t nat -A POSTROUTING -o wg0 -j MASQUERADE\n
      </span><span style="color:#323232;">PostDown = iptables -t nat -D POSTROUTING -o wg0 -j MASQUERADE\n
      </span>\n
      ```\n
      \n
      and restarting the wg connection, I’m seeing traffic on the ens3 port but none entering wg0 via tcpdump. I feel like I probably have conflicting iptables rules saved [pastebin.com/0eNwhNKM](https://pastebin.com/0eNwhNKM) but I don’t really know enough about whats going on there to fix it. I feel like its probably the wireguard-*-rule ones (created by pivpn possibly?) but I’m not sure.\n
      \n
      Edit way later: Ended up just using rinetd for the udp connections. Ubuntu doesn’t include the latest version here [github.com/samhocevar/rinetd](https://github.com/samhocevar/rinetd) which *is* able to do UDP connections. The docker container RxBrad suggested uses that version within the docker container to make the redirections so it will be roughly equivalent.

    +title: "Issues forwarding traffic through a wireguard connection"
    +url: null
    +body: """
      I am attempting to follow this [procustodibus.com/…/wireguard-port-forward-from-i…](https://www.procustodibus.com/blog/2022/09/wireguard-port-forward-from-internet) to forward traffic from a few ports on a public oracle vps to other ports on my local server through a wireguard connection. Currently I am doing this using rinetd, but I was looking for a more normal way of forwarding traffic. (Also looking to forward UDP traffic at some point.)\n
      \n
      After stopping rinetd, adding these rules to the public server’s wg config\n
      \n
      ```\n
      \n
      <span style="color:#323232;"># packet forwarding\n
      </span><span style="color:#323232;">PreUp = sysctl -w net.ipv4.ip_forward=1\n
      </span><span style="color:#323232;">\n
      </span><span style="color:#323232;"># port forwarding\n
      </span><span style="color:#323232;">PreUp = iptables -t nat -A PREROUTING -i ens3 -p tcp --dport 443 -j DNAT --to-destination 10.144.65.2:8443\n
      </span><span style="color:#323232;">PostDown = iptables -t nat -D PREROUTING -i ens3 -p tcp --dport 443 -j DNAT --to-destination 10.144.65.2:8443\n
      </span><span style="color:#323232;">\n
      </span><span style="color:#323232;"># packet masquerading\n
      </span><span style="color:#323232;">PreUp = iptables -t nat -A POSTROUTING -o wg0 -j MASQUERADE\n
      </span><span style="color:#323232;">PostDown = iptables -t nat -D POSTROUTING -o wg0 -j MASQUERADE\n
      </span>\n
      ```\n
      \n
      and restarting the wg connection, I’m seeing traffic on the ens3 port but none entering wg0 via tcpdump. I feel like I probably have conflicting iptables rules saved [pastebin.com/0eNwhNKM](https://pastebin.com/0eNwhNKM) but I don’t really know enough about whats going on there to fix it. I feel like its probably the wireguard-*-rule ones (created by pivpn possibly?) but I’m not sure.\n
      \n
      Edit way later: Ended up just using rinetd for the udp connections. Ubuntu doesn’t include the latest version here [github.com/samhocevar/rinetd](https://github.com/samhocevar/rinetd) which *is* able to do UDP connections. The docker container RxBrad suggested uses that version within the docker container to make the redirections so it will be roughly equivalent.

      +title: "Issues forwarding traffic through a wireguard connection"
      +url: null
      +body: """
        I am attempting to follow this [procustodibus.com/…/wireguard-port-forward-from-i…](https://www.procustodibus.com/blog/2022/09/wireguard-port-forward-from-internet) to forward traffic from a few ports on a public oracle vps to other ports on my local server through a wireguard connection. Currently I am doing this using rinetd, but I was looking for a more normal way of forwarding traffic. (Also looking to forward UDP traffic at some point.)\n
        \n
        After stopping rinetd, adding these rules to the public server’s wg config\n
        \n
        ```\n
        \n
        <span style="color:#323232;"># packet forwarding\n
        </span><span style="color:#323232;">PreUp = sysctl -w net.ipv4.ip_forward=1\n
        </span><span style="color:#323232;">\n
        </span><span style="color:#323232;"># port forwarding\n
        </span><span style="color:#323232;">PreUp = iptables -t nat -A PREROUTING -i ens3 -p tcp --dport 443 -j DNAT --to-destination 10.144.65.2:8443\n
        </span><span style="color:#323232;">PostDown = iptables -t nat -D PREROUTING -i ens3 -p tcp --dport 443 -j DNAT --to-destination 10.144.65.2:8443\n
        </span><span style="color:#323232;">\n
        </span><span style="color:#323232;"># packet masquerading\n
        </span><span style="color:#323232;">PreUp = iptables -t nat -A POSTROUTING -o wg0 -j MASQUERADE\n
        </span><span style="color:#323232;">PostDown = iptables -t nat -D POSTROUTING -o wg0 -j MASQUERADE\n
        </span>\n
        ```\n
        \n
        and restarting the wg connection, I’m seeing traffic on the ens3 port but none entering wg0 via tcpdump. I feel like I probably have conflicting iptables rules saved [pastebin.com/0eNwhNKM](https://pastebin.com/0eNwhNKM) but I don’t really know enough about whats going on there to fix it. I feel like its probably the wireguard-*-rule ones (created by pivpn possibly?) but I’m not sure.\n
        \n
        Edit way later: Ended up just using rinetd for the udp connections. Ubuntu doesn’t include the latest version here [github.com/samhocevar/rinetd](https://github.com/samhocevar/rinetd) which *is* able to do UDP connections. The docker container RxBrad suggested uses that version within the docker container to make the redirections so it will be roughly equivalent.

      +title: "Issues forwarding traffic through a wireguard connection"
      +url: null
      +body: """
        I am attempting to follow this [procustodibus.com/…/wireguard-port-forward-from-i…](https://www.procustodibus.com/blog/2022/09/wireguard-port-forward-from-internet) to forward traffic from a few ports on a public oracle vps to other ports on my local server through a wireguard connection. Currently I am doing this using rinetd, but I was looking for a more normal way of forwarding traffic. (Also looking to forward UDP traffic at some point.)\n
        \n
        After stopping rinetd, adding these rules to the public server’s wg config\n
        \n
        ```\n
        \n
        <span style="color:#323232;"># packet forwarding\n
        </span><span style="color:#323232;">PreUp = sysctl -w net.ipv4.ip_forward=1\n
        </span><span style="color:#323232;">\n
        </span><span style="color:#323232;"># port forwarding\n
        </span><span style="color:#323232;">PreUp = iptables -t nat -A PREROUTING -i ens3 -p tcp --dport 443 -j DNAT --to-destination 10.144.65.2:8443\n
        </span><span style="color:#323232;">PostDown = iptables -t nat -D PREROUTING -i ens3 -p tcp --dport 443 -j DNAT --to-destination 10.144.65.2:8443\n
        </span><span style="color:#323232;">\n
        </span><span style="color:#323232;"># packet masquerading\n
        </span><span style="color:#323232;">PreUp = iptables -t nat -A POSTROUTING -o wg0 -j MASQUERADE\n
        </span><span style="color:#323232;">PostDown = iptables -t nat -D POSTROUTING -o wg0 -j MASQUERADE\n
        </span>\n
        ```\n
        \n
        and restarting the wg connection, I’m seeing traffic on the ens3 port but none entering wg0 via tcpdump. I feel like I probably have conflicting iptables rules saved [pastebin.com/0eNwhNKM](https://pastebin.com/0eNwhNKM) but I don’t really know enough about whats going on there to fix it. I feel like its probably the wireguard-*-rule ones (created by pivpn possibly?) but I’m not sure.\n
        \n
        Edit way later: Ended up just using rinetd for the udp connections. Ubuntu doesn’t include the latest version here [github.com/samhocevar/rinetd](https://github.com/samhocevar/rinetd) which *is* able to do UDP connections. The docker container RxBrad suggested uses that version within the docker container to make the redirections so it will be roughly equivalent.
