      If you know you're hijacking why not just start another thread?

      DO NOT set a source address/port in a port forward or firewall rule unless you KNOW you need it!

        because it might be the same issue/bug and it will be easier to search for that ... ? sorry

          I masked the WAN-IP of the SG-3100 ... looks good to me aside from traffic going through.
          Same tunnel worked already earlier today ... I can log in to the SG-3100, ping to WAN is fine.

            The only bug in play is what looks like issues in the async crypto in yet-to-be-identified edge cases.

            Everything else is almost certainly misconfiguration.

              Looks fine. How are you testing?

              Did you install any policy routing on the LAN rules?

                @derelict no, I did not. So far I ping from pfsense and my system behind.
                You know what? Now that I stopped IPSEC completely after disabling everything execpt that one tunnel ... waited some minutes and started the IPSEC service again, it starts pinging again.
                I will monitor this for the next few days .. Thanks so far.

                  When you ping from pfSense you have to be sure to source it from something interesting to IPsec. Use the -S flag or the Source address pulldown in Diagnostics > Ping.

                    will do, thanks. So far I mostly tested from my laptop (within LAN).

                      To be fair and maybe even help others here additional information:

                      It turned out that my local docker-installation sometimes used a subnet 172.20.0.0/16 that overlapped the subnet behind the pfsense-IPSEC-tunnel to my customer. So this lead to routing tables on my local machine pointing "somewhere else". The IPSEC-tunnel was working all the time. Thanks anyway.
