When abroad, I use a Turris Omnia router to connect to internet and use WireGuard to connect to home.
On IP addresses everything is reachable at home, but when using DNS names, the names can not be resolved. I have a PiHole server (reachable when pinging on IP and also when manually querying DNS on PiHole from my laptop connected to the wifi of the Turris Omnia and also from the CLI on the Turris Omnia) running at home serving as DNS.
I tried adding the local domain name and IP-address of PiHole to the “DNS Forwardings” section in “DHCP and DNS”, but that doesn’t solve it.
Is there something else I can do to make the Turris Omnia forward DNS queries for the local domain to PiHole?
