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?

      Thanks, looking at it now, but I should have remembered, iptables has a separate tool for ipv6 called ip6tables. Could you also paste the output of

      ip6tables -L

      If you put it in the comment between backticks like this:

      ```
      <paste here>
      ```

      then it will keep the formatting exactly as it was when you copied it, instead of munging the linebreaks.
