Hi guys, hope somebody can help me with a problem. I have a few services on my homeserver that I want to be only accessible from either inside my home network, or while being connected to it with a Wireguard server that runs on my router. I can perfectly access my homeserver with its local IP address 192.168.x.y when connected with the VPN. Now I would like to be able to access it with the domain test.example.com which has its A record pointed at 192.168.x.y. This works when I am inside my home network, but not through my VPN.
Is what I am trying to do infeasible? On my client the Wireguard config has AllowedIPs=192.168.x.0/24,0.0.0.0/0, hence I can reach the homeserver via 192.168.x.y, but why does it not work via domain name through the tunnel? What does however work is editing the hosts file on my client to point test.example.com at 192.168.x.y, but I would prefer not to do so. Any ideas? Thanks in advance
Removing 0.0.0.0/0 didn’t really change anything, apparently on Linux (maybe specifically for wireguard?) 0.0.0.0/0 does not catch the local ip address ranges. However it was a DNS issue it seems; the default wireguard config that my router gave me for clients had DNS set to the router’s IP which generally speaking worked (I could browse the web with 0.0.0.0/0 in AllowedIPs on client) but for some reason it doesn’t resolve my domain correctly.
Anyways I’m gonna settle with only 192.168.x.0/24 in AllowedIPs, since I don’t really need a full tunnel, and DNS=1.1.1.1 in client config. Maybe I’ll eventually set up a pihole but I’m not so keen on doing that for now. Nonetheless thanks :)
