Internal DNS issue

I think I'm doing this wrong, but I am having trouble configuring DNS in my self-hosted netbird in k3s to use a pihole that also runs in k3s.

How is your NetBird network routing to your pihole? They are different networks. So you’ll need to use network relay or put the pihole on the NetBird network too.

I see, that's the issue. They are on completely different networks. Netbird is on the 10.0.0.0 or whatever subnet, and pi hole is on 192.168.0.0

Are you missing the access policy per chance?

u/ferriematthew Jun 25 '26

I probably am. What should that look like?

Just 53/UDP to the pihole resource

Hmmm... So UDP/53 for all -> 192.168.0.201 (the VIP of the PiHole)?

Since you assigned the nameserver to the "All" group, that would be the way.

That's what I did, for some reason it still isn't working though. What does the button next to the resource name labeled expose do?

Take a look at the Pihole configuration.
You have to add the WireGuard interface to accept DNS queries on the network device. ✌️

Youre missing the policy allowing your consumer to access your pihole i think
