I just setup Unbound DNS on my home server (read: old laptop screaming for dear life next to my router). Everything is working well, I can access it and use it as my DNS server on my desktop which is connected to the same network as my server.
The issue is with trying to get my phone to use Unbound while connected to the same laptop through Wireguard. If I’m connected to the Wi-Fi and disconnected from Wireguard, I can nslookup on my phone using the Unbound server, but as soon as I’m connected through Wireguard it can’t access the DNS server.
I suspect it has something to do with the fact that I run Wireguard through Docker but Unbound is setup directly on the host machine, and the container isolation is what’s causing my issues. However, I tried adding
extra_hosts:
- "host.docker.internal:host-gateway"
to my docker-compose.yml for Wireguard, and tried accessing the DNS using the host IP inside the docker interface, but it didn’t work.
Does anyone have any leads or tips on how to properly configure this? Thanks in advance!
I could do that, but I want to avoid opening ports on my router’s firewall apart from the one necessary for Wireguard. I can access all my other stuff through Wireguard, but I can’t wrap my head around why it seemingly can’t access Unbound on the local host.
Well that’s how the Internet works, bud. You’re opening a port for WG to start. Either make that work and correct your routing, or find another solution.
You’re not going to be stealthy by making this overcomplicated. You’re just adding extra steps. You don’t want to use DHCP to its benefits locally, and you don’t wantbto open ports…what magic do you want to happen here?
I’d rather not open ports I don’t have to. I don’t see why I’d have to open a port when Unbound works on my local network and I have access to my local network via Wireguard. I can access a whole slew of services through that one Wireguard port, why wouldn’t Unbound work?
Thanks anyway for trying to help, bud.
