    @luckman212 sadly I only have one NIC on the workstation that I have pfsense on. (However in reality siteA will be behind NAT)

    Yes I do have direct access to the SiteB, you want me to use SonicWall for the IPsec instead pfsense?

      @gabacho4 and @luckman212 also for your information when I check the port with the Public IPs:

      SiteB is open,

      But SiteA is closed! do you think this is what makes the problem? and since it's a simple internetBox I do not have a firewall to ope the ports at all.

            @gabacho4 now both sides are running on 2.6.

            But still not working!

            For your information when I check the port with the Public IPs here https://www.yougetsignal.com/tools/open-ports/:

            SiteB is open

            But SiteA is closed! do you think this is what makes the problem? and since it's a simple internetBox I do not have a firewall to ope the ports at all.

              @ibnkamala sorry just got home from work. So it appears in the last screenshot that both the P1s are connected. That would seem better than it was before. Can you show me the logs so I can see what the P2 is doing? I’m not going to lie to you, your setup is insanely more complicated than I’d ever use. Why would you have pfsense behind another firewall and other hardware? And what is an internet box? A modem? A router? An ONT?

                @ibnkamala Ok so I did some Googling. Are you located in Switzerland? I find a internetBox that the ISP in Switzerland offers. If not Switzerland perhaps you are in another European country where the internetBox is used. If you have the device I have found, you can most certainly do port forwarding and/or set up a DMZ. I can't find anything about Ipsec passthrough but it's either there or a DMZ/port forwarding would get the job done.

                Some advice - except for art, less is not more. I'm a little tweaked to find out you're using virtualized instances of pfsense that are behind multiple devices etc. Should have asked more about your setup at the beginning but for the next time, cough up all the details from the get go please.

                    @ibnkamala can you go to Status - System Logs - Settings and change the GUI log entries from 50 to 500?

                          OK then note what I said about being able to port forward or set up a DMZ. Your device should have documentation that shows how to do this.

                              @gabacho4 I have already port forward in place, https works fine I am even able to access publicly the pfsense gui, and since I have not change the pfsense ipsec default ports which I think it uses 500 and 4500 so I have crteated below reules.

                              9b79554c-c983-4300-a2b0-2e983613cd3b-image.png

                                @gabacho4 in my real configuration I will be using https://shop.netgate.com/products/6100-max-pfsense instead of SiteA but still will be behind NAT and won't be here in France it will be in Barcelona

                                Concerning the SiteB / there won't be any changes. which will happen in 3 days. on Th 16th of June. but for behind a proper firewall and router.

                                But I wanted to do the manipulation to see how it works, but sadly I am not there yet :)

                                  @ibnkamala I don't see that the port forwarding allows the esp protocol through. This is why most internet devices support IPsec passthrough. Can you put the Pfsense box on a DMZ and then try. Looking at your logs, it looks like SiteB tries to connect to SiteA but never gets a response. Would seem to indicate to me that things are not getting through.

                                      Now that both boxes are on 2.6, may I suggest switching to WireGuard since it is more NAT friendly, and requires just a single UDP port to be forwarded. You can try this without disturbing the IPsec config you have done so far (just disable the P1 to test)

                                      https://docs.netgate.com/pfsense/en/latest/recipes/wireguard-s2s.html

                                        @luckman212 what do you mean exactly I have to disable phase1 in both sites, then how can we test ? I will forward simple to the Pfsense.

                                          @ibnkamala I am saying: forwarding the ports and protocols needed to make IPSEC work in a double-NAT scenario (such as you have) is not an easy task. It seems you might be a little over your head with it.

                                          So, I suggested changing strategy and trying Wireguard, which is a completely different protocol, to establish the site-to-site tunnel. I posted a link to the guide so you could try to set it up.

                                          If you do give that a try, just stick to the default port (udp/51820) and forward that port from "Simple Internet Box" to your inside SiteA pfSense, and also forward from SiteB Sonicwall to pfSense. It's just another possible solution.
