      @thisisme I am trying right now and for me it is also not working. It is new for them too, maybe they have problems on their side.
      Will report here if this changes for me.

        Just to point it out: I don't had to add firewall rules to the Wireguard tab. This advice is WRONG and DANGEROUS

          @thisisme Ping and DNS seem to be working for me. I didn't tested DNS within pfSense but just in a Windows VM. But I can't surf anything.

            @bob-dig have you set the MSS on the Wireguard interface?

              @thisisme No, I don't think it is a must anyways.

                    @bob-dig 1412 seems to work. Maybe you have to play a bit

                      Solved my DNS problem. Looks like wireguard is not adding any routes. I had to add a manual one for the DNS-Address and the gateway

                        Got it working too, thanks for the MTU hint!!
                        I went with 1420. Without it, it wasn't working.

                        I didn't need any routes but my setup is different. Also no manual outbound NAT needed, see below.

                        For IP I went with /32 and changed the IP for the second tunnel myself.

                          Something to note when using Surfshark VPN on pfSense with WireGuard instead of OpenVPN.

                          You decide which IP will be used > no more overlapping IPs with different tunnels. 👍

                          No good GUI support for changing the public IP of one tunnel, you have to restart the whole WireGuard service for all the tunnels to change IPs and it takes much longer for a new connection (but it is possible). 👎

                          In my testing, speed was the same with my hardware.

                            @thisisme I noticed that the performance is lower with WG on ss, more loss etc. What is your experience so far?

                              @bob-dig I don't see any performance loss. Maybe even a little gain, but hard to say, because the last 15mbit to my full bandwidth are a bit unstable with Surfshark with both approaches.

                                @thisisme Probem for me it is packet loss, not the speed. I kinda remember that even in their own app, WG is working worse then OVPN, so I will switch back... 😢 YGWYPF

                                  @bob-dig since 2 hours I have a lot of loss too. Since then it was always below 10%. I think the Surfshark servers are unstable or overloaded

                                    @thisisme Back on OVPN, so much better. It was a short endeavor. I think their WG implementation is just bad, for years now.

                                      @bob-dig packet loss with WG close to zero again for me

                                          My surfshark wireguard configuration is not working. I'm sure it must be something incredibly obvious, but I can't figure it out.

                                          Can someone please scan the config below and let know what is missing. For testing I have it configured like @Thisisme 's example.

                                          fyi .... I am using selective routing and have a couple of LAN devices that are configured with firewall rules to only route to the surfshark wireguard gateway. Also, my OpenVPN config is fine.

                                            @matosc Do you have two Gateways for that connection?

                                            Today I noticed that pfSense isn't really doing any cleaning with gateways when I removed all OVPN connections and later removed all WG connections...
                                            OVPN runs great with ss. I think it is even using DCO but I am not sure.
