      Same deal - logs are on fire. I really wonder if I'm trying something that isn't fully implemented in pfsense/freebsd. I've done a ton of web searches and haven't been able to find anything that matches. Part of me wonders if site A forgets or cannot remember/track the connection and so when something comes back from the internet the router at site A it says "what's this request for 192.168.2.2?" and then blocks it or parts of it.

        Show me what the command shows
        pfctl -sr | grep enc0

          pass out on enc0 all flags S/SA keep state label "IPsec internal host to host"
          pass quick on enc0 inet all flags S/SA keep state label "USER_RULE"
          pass in quick on enc0 inet all flags S/SA keep state label "USER_RULE"

              So firewall is still having events however now the interface has changed from ipsec to IPSEC_VTI. ???

                @ngoehring123 said in Can I route internet traffic from site B through site A via Ipsec VTI?:

                IPSEC_VTI

                That's the same floating rule , but for IPSEC_VTI ?
                There will be two identical rules , one for IPSEC and the other for VTI

                  I just have the one floating rule for ipsec. When I made those last changes you suggested the firewall errors started saying IPSEC_VTI instead of ipsec. I had to disable those last changes as they resulted in me losing access to the remote router. Thank goodness for openvpn. 😊

                    Excuse. I didn't think there would be such a result. I have no more ideas )))

                      No worries my friend. Your time and effort is greatly appreciated. Here's to hoping this gets sorted out soon. I'll be sure to share the fix with you. Thanks again!

                        I would consider an option of the usual IPSEC tunnel, through it too it is possible to pass a traffic outside.

                        https://docs.netgate.com/pfsense/en/latest/vpn/ipsec/routing-internet-traffic-through-a-site-to-site-ipsec-vpn.html

                          I had thought of doing that as well but really like the routed option more due to its flexibility and power. Perhaps @jimp has some tips for me.

                              That's possible. I myself use the GRE over IPSEC option and do not want to switch to VTI yet.
                              Will wait to hear other forum members

                                In this forum, I read that some remove the VTI interface, re-create the tunnel , and the problems are solved

                                  I'll give that a go. After everything else, it won't hurt!

                                      I did not. Last thing I tried was to remove the interface, delete the static routes, and the remove the p1 and p2 and do it all over again. No luck. So I went back to openvpn. I was super excited to use the ipsec route instead due to the better throughput and all.

                                        Openvpn is cool , but unfortunately Iran's government filter it here, so we must find another solution.

                                          Yeah I'm in a part of the world where I want the anonymity as well. Have you tried openvpn on port 443? Or does Iran filter on something more specific?
