DNS is not resolving from VPN (Wireguard and OpenVPN) on Slate AX GL-AXT1800

Here is the log file. Thanks.

I found:

-A zone_lan_prerouting -p tcp -m tcp --dport 53 -m comment --comment "!fw3: Force DNS" -j REDIRECT --to-ports 53
-A zone_lan_prerouting -p udp -m udp --dport 53 -m comment --comment "!fw3: Force DNS" -j REDIRECT --to-ports 53

This rule is not necessary while VPN is on.

You can drag these two Firewall - Port Forwards rules before the Force DNS rules. i.e. give them higher priority. Or disable "Force DNS" rules.
