My current setup has my DHCP + DNS on my Unifi USG. However, as I have all my apps hosted on a different server (unifi, plex, home assistant, NAS, etc.) I’ve ran into issues trying to get things set up....
So this is where I’m a little confused. The USG had the option to assign a static IP (which I’ve done), but if you ever need to CHANGE that IP… Chaos. From what I understand the USG needs to propagate that IP to all your devices, but it uses the controller to do that. Then you also run into issues with IP leases having to time out. Same problem occurs if I ever upgrade my server and change out the MAC address. Because now the IP is assigned to the old MAC.
I’m not sure if there’s any way around this. But it basically locks me in to keeping the controller (and thus my server) at a single, fixed IP, without any chance of changing it.
Is there any specific reason you need DHCP to assign an IP to your main hosting server vs setting it all statically?
I’ve done this. I think the real problem is if I ever change the server MAC or IP, as now the unifi server isn’t picked up by the USG, which means I can’t change the static address.
Damn, I didn’t realize the amount of hate for DHCP. Ive used an already configured system with a DHCP/DNS server set up and it was super easy to manage. Want to change or add a static IP? Edit the text file, add the MAC, reload.
I didn’t know this wasn’t reflective of the overall experience.
Should I use a dedicated DHCP/DNS server hardware
