          If there's nothing else I can do, I would switch back to 2.1.5  :(

            we switched back to strongswan 5.2.1 yesterday after some issues with 5.2.2 (the change to which coincides with the date of the problems you're seeing). Upgrade to the latest available now and let us know.

                      This happens even when you are initiator?

                      I belive your other side is coming on your other interface while you expect it on WAN?

                        I think this end is initiator and responder, b/c the other side opens the tunnels as well.
                        BTW I already did a packettrace on the "other" interface to see if there's traffic (UDP&port 500) coming or going.
                        Nothing !
                        But I can check the other Pfs 2.1.5 tomorrow.
                        I deliberately change the tunnel to this other IF and check the the dyn address points to the correct IP and IF.

                          Update:
                          Just check the 2.1.5 side and no packets go to the wrong Public IF of the 2.2.

                              What NAT again? You've already been told you cannot NAT IPsec.

                                  And BTW a just captured packets on my WAN and could see ISAKMP (Main Mode) going forth and back between both pfsenses.

                                      @doktornotor: Checking my reply, I said I remove "any NAT rules" meaning the ones I manually created !
                                      But as known, the "Automatic Outbound NAT rules" persist due the mode !
                                      So I'm pretty sure that if config is correctly interpreted by pfSense no manual rule should interfere.

                                      But my Question was if any of the other inbound rules could interfere with VPN ?
                                      Do you have an answer for this ?

                                        The automatic outbound NAT rules won't hurt anything with IPsec.

                                        For inbound, if you have a port forward on UDP 500 or ESP traffic, that'll break it also. If you have a 1:1 NAT using the public IP where it terminates, that'll forward the traffic to an internal host and break things as well.

                                          Hmm, thanks, but I can't find any inbound NATs with 500.
                                          Maybe we should look at it using our old support contract ?

                                            Commercial support is definitely the best answer. Your support expired over 5 years ago though, if you purchase to activate support on your account again, we can definitely assist.
