DNS doesn't work with AirVPN DNS

[rasmus-kirk]

Describe the bug
The DNS provided by AirVPN doesn't work. This has been reproduced in different Nixarr configurations. I get the same bug if I remove Nixarr completely from my machine and just run this VPN-module.

I had a similar issue with mullvad vpn, all torrents were giving me an error Couldn't connect to tracker.
Not sure if it's the best/right approach, but I have managed to sort it out using a different DNS (9.9.9.9) in the wireguard.conf file provided by mullvad.

I haven't encountered this problem myself, but running some diagnostics could help pinpoint where the packets are dropped.
Could you try running the following command?

sudo ip netns exec wg bash -c "nslookup google.com; dig google.com; traceroute google.com; iptables -nvL"

Hopefully this will give some insights.
