      You have a P1 mismatch of some sort.

      found 1 matching config, but none allows pre-shared key authentication using Main Mode

        I noticed that. Checked and re-did configs three times. There's no way there's ACTUALLY a mismatch. How do I "flush" this thing, it's got something sitting somewhere that's messed up. I used the same password as I had previously. It makes no sense!

          Try this-
          Stop the service.
          Make sure it's dead by checking with ps. Kill any charon or ipsec starter proceses.
          Check /var/run delete charon.*
          Restart the service.
          Rebooting the firewall may work as well.

            A stop, then start of the IPsec service would suffice to clear out anything that was in place before (or reboot if you want). There won't be any processes or files or anything else left behind that matter, I wouldn't recommend dotdash's suggestion. No harm in doing exactly what he stated but if you're excessive with deleting things you might break other things, and it's not necessary to delete any of that.

            You probably have one side on main mode and the other on aggressive to get the logs you're getting.

              I've tried both in main mode and in aggressive mode (which was the original working mode before the upgrade). I set both to aggressive mode and rebooted both firewalls. Hmm, at a loss here. Looks like it's the same.

                Tried dotdash's suggestion

                [2.2.4-RELEASE][admin@pfsense.tcfedina.local]/root: Check /var/run delete charon.*
Check: No match.
[2.2.4-RELEASE][admin@pfsense.tcfedina.local]/root:

                Rebooting didn't help. Do I need to just go back to a previous firmware? …and if so, how do I do this?

                  Diving deeper into what's running the backend I see that raccoon was replaced with strongswan. Looks like a bad move, but whatever. I see this strongswan issue: https://wiki.strongswan.org/issues/956 but the resolution won't work, I cannot locate /etc/ipsec.conf … anyone have any idea where ipsec.conf is?

                    I wanted to point out that 'aggressive = yes' in both the files.

                      To restate my original question, can someone please post what they're doing to get this working on 2.2.4. Looking at strongswan's ipsec.conf suggestions (https://www.strongswan.org/uml/testresults/ikev1/net2net-psk/), compared with the configuration populated by pfsense suggests to me that this isn't going to work at all.

                        Disabled the service, tried to change the handshake for phase 1 to certificate, but couldn't get it to work. Changed it back to psk, changed encryption type to blowfish and DH to 5 from 2 (honestly, just because I was bored). Started the service back up, and it reconnected… holy crap, I hope I never have to come back to this forum again! Down with PFSENSE!
