        You didn't select a source interface as I said otherwise it would show that. That traffic won't go over the VPN unless the source IP matching the local subnet selector.

          Sorry Steve. I did overlook that request.

            Might be a shot into the dark, but what are your firewall rules for IPsec? Did you add rules for the new tunnels?

              Ok so that target may not respond to pings or is blocked etc but did you see 10 packets on the Phase 2 status outbound?

              Traffic from the firewall itself should always be allowed out across the tunnel. Unless you have specific blocking 'OUT' floating rules.

                at this point for testing I have a very open rule set on both ends.
                As for traffic It doesn't even display the phase2 for ipsec tunnels

                  Your screenshot above shows the Phase 2 as established but the traffic counters show 0 packets in or out. After running that ping it should show 10 packets out.

                      Please run the ping test again and post another shot of Status > IPsec with the phase 2 expanded. Thanks.

                        another thread-hijacker here:
                        I see issues on a tunnel between my 2.4.4 SG-1000 and a remote SG-3100 on 2.4.3-p1 still.

                        tunnel comes up, no traffic goes through .. no ping via shell, nothing seen in Status page.

                        disabled that new async-option, checked and upgraded strongswan (on SG-1000), re-saved tunnel configs, restarted IPSEC ... I will disable other tunnels and check back with a screenshot or so.

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

                            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.
