Hi all—as title suggests I’m experiencing a compatibility issue between UFW and my vpn (Windscribe if it matters). My UFW defaults are set to deny incoming, allow outgoing, and routed disabled, with no exception rules configured. When I enable Windscribe (I use OpenVPN udp on port 80 if that matters) while UFW is active, Windscribe reports a network configuration error and requests sending debug logs; ignoring the error still allows the VPN to function, but I observe IPv6 and DNS leaks. Disabling UFW removes the error and the leaks. What UFW configuration is causing this behavior, and which specific rules should I add to prevent IPv6 and DNS leaks while keeping UFW enabled?

    Sorry to be a doofus, but could you paste the output of iptables-save and ip6tables-save instead? The default iptables output actually just leaves out important information like which interface the rule applies to.

    I think the best thing to do would be to see if you can get support from Windscribe and find out whether it’s a known issue or a bug that needs fixing.
