I’m having issues with DNS when I try to connect to my HA instance remotely using the Wireguard community addon together with Adguard Home.
In the Wireguard addon, I have 172.30.32.1 configured to use for DNS (as suggested in the Wireguard addon docs). I don’t have any specific entries for allowed IPs or client IPs.
When I connect to Wireguard remotely, I am able to access local addresses in a browser on my mobile device, so it seems like the Wireguard connection itself is functioning. However, while connected to Wireguard, I can’t access any external sites at all. The browser reports name resolution failure. As soon as I disconnect from Wireguard, all works as expected.
When on home Wi-Fi, I’m using Adguard for DNS for all devices, and all seems to work fine for Internet access and ad blocking.
So, there seems to be some issue specific to the interaction between Adguard Home and Wireguard.
Any guidance is appreciated.
HA Instance Info:
Wireguard addon 0.5.0
Adguard Home addon 4.0.0
