      I have 4 ipsec tunnels connecting to my pfsense only 1 of them is having issues connecting as if pfsense is just blocking the one when they are all set up the same. We recently had a outage with AT&T at that site but it came up just fine for days before this. I have updated firmware rebooted etc nothing works all the settings look correct. The only thing I can find out of the norm is modp 1024 configured and 1536 recieved. dh group in phase 1 is set for 5 i have the screen shot for phase 2 attached.

        It is as if Pfsense is setting it for dh2 in the second phase even though I have it set for none. So I changed the setting in the pfs key on both sides to none then 2 and 5, fails every time.

          That looks to me like your Phase 1 is configured for group 2 and the other side is expecting group 5.

            Yeah that is the weird thing, the logs are showing that but the settings are set for 5 on both sides. See attached any ideas should I reboot pfsense after hours tonight?

              No need to reboot. If anything stop and start the ipsec service. Don't restart, stop and start.

                Its so strange as Pfsense has been so reliable and I have 3 other sites that are connecting with the exact same config and connecting fine.

                I am remoted into the remote router its a zyxel and it seems to be running fine with the exception of getting timed out each time I try to connect.

                I even set up for aggressive on both sides and changed to dh2 just to see if it did anything but it gave the exact same error.

                  Yeah stop stabbing around at checkboxes that make no difference.

                  Is this 2.3.4_1?

                      I don't know of anything that would affect that but maybe you should get current.

                      PM your /var/etc/ipsec/ipsec.conf and that output from ipsec statusall

                      If the logs have changed it might be helpful so see fresh ones, too.

                        will pm you know I even set up a completely new connection on pfsense and the remote router. Pfsense is still stuck on wanting dh2 in phase 1 for some reason so i matched on the remote site and got a pseudo random function found. see below

                          That is set MD5 on one side and SHA1 on the other.

                          
These do not match:

                            I set them both to match but its like pfsense is sticking. I am going to have them all set sha1 but that is saying it doesn't support a preshared key in the log stand by i have to drive home then will try and repost logs feels like i am closer at least.

                              There are settings that do not take effect until rekey/reauth or the tunnel is torn down and brought back up. IPsec is generally set it and forget it so it likes to keep the tunnels up.

                                Yeah for all my other sites it has been set it and forget it so I set up another tunnel to see if that fixed it but it just seemed to have other issues. The most i have had to do up til now is reset the unit usually just need to reconnect VPN.

                                here is the most recently logs as i went back to that tunnel. i changed the designation to be pfsense and remote also both are set for dh5 for phase1 and none for phase 2

                                    Is it still set for aggressive mode? Set it to Main.

                                    I won't know what con5 is until I get those config files and output in the PM.

                                      I copied settings from other working tunnels but it is saying it is DH2 on phase 1 when I have DH5 selected. They are all set for Main.

                                      Can I give you those outputs via the gui? I dont have shell enabled and don't know the commands.

                                      If I have too I can restart the pfsense router tonight.

                                        It looks like those connections are matching your Mobile IPsec somehow. Is the other side set to be aggressive mode?

                                        I see it says Main mode up there. but that's what's happening…

                                        Are you sure about that remote source IP address?

                                          Turns out as strange as it was pfsense was somehow stuck on dh2 for phase 1. I had to reboot pfsense and it fixed the problem even though no configs had changed and 3 other sites were connected in exactly the same way the unit had been up for almost 300 days though without reboot. Can't figure out how to mark as solved maybe thats left for moderators?
