      Im getting the same issue. Afer a reboot the tunnels all come up and work for a few minutes, then they all fail.

      These are all pfsense to pfsense site-to-site tunnels. So just as a test i updated one of the other ends to 2.3 but that made no difference either. I have also rebuilt both sides of the tunnel but still no joy.

      One thing im a bit confused about is the recieved proposal is wrong. But i 100% sure the other side is correct. (actually, this might be a red herring, think its related to another tunnel)

      Luckily this isnt production, just my home.

        similar problem here. After some fiddling (IPcompression off, using other proposals, disabling crypto module) the tunnels came up in the end with the same settings they had before (!?)  but they are passing no traffic  :-[.

        Some sites are working from the start with different devices on the other side (cisco sbs, zywall, pfsense 2.2.6) but all others are up passing no traffic.
        Most of the non working tunnels are on Alix or APU Boards with GeodeLX-crypto so all of them are on AES128 proposals (any thoughts).

        Build up a fresh testdevice on an APU-Board with pfSense2.3 which showed the same behaviour first but after disabling IPcompression and rebooting it seems to work now.

        • LX Security Block is loaded
        • AES 128 - SHA256 - DH2 on P1 and P2
        • IPCompresion off

        seems to work between 2.3 and 2.3 but not between 2.3 and 2.2.6.
        I can't see any consistency in this …  ???

        If there are any ideas what to try or to check/log - I can have a look on reproducing it and report back.

          Are these all 2.3 systems which were upgraded from 2.2.x or fresh 2.3 installs?

            Same problem here with 2.2.6 upgrade to 2.3, IPsec tunnel is reported up but no traffic is flowing.

              @kapara:

              Are these all 2.3 systems which were upgraded from 2.2.x or fresh 2.3 installs?

              only one system updated from 2.2.6 to 2.3
              all other systems are 2.2.4 or 2.2.6

              in the meanwhile I've got one 2.2.6 install running again with traffic throughput … but I've got NO IDEA WHY it is running again ???

              Later today i will try to delete some of the IPsec endpoints on both sides and configure them from the scratch ... let's see what happening.

                If you're getting either of these messages:

                error sending to PF_KEY socket: No buffer space available
no socket implementation registered, sending failed

                The root cause is here:
                https://redmine.pfsense.org/issues/6160

                the commit on that ticket will fix the root cause. Or if you want to manually fix quickly, run the following:

                killall -9 charon
killall -9 starter 
ipsec stop
ipsec start

                It'll probably still happen again at your next reboot on systems that happen to be unlucky enough to hit that race condition, but will work until then.

                  I can confirm what Chris has referenced above.  Prior to seeing his post I did indeed notice that there were two instances of charon running in the process list.  The moment I killed one of the processes the tunnels popped right up.

                  I can also confirm that upon reboot there are, once again, two instances running and the problem returns.  Kill the procs and all is well again.

                    Thanks. If you apply this change either manually or using the system patches package, it'll fix.

                      Manually made this change. Looks to have fixed it for me. Nice Job!

                      EDIT

                      Come back a few hours later, all tunnels down again. Im doing some investigating to see if this is a continuation of previous issues.

                      Yeah, still getting the exact same error.

                      I stil get it after doing:

                      
killall -9 charon
killall -9 starter 
ipsec stop
ipsec start

                      I double checked my /etc/inc/vpn.inc and it DOES have the changes still there.

                      Any suggestions?

                            I have the same issue.

                            The fix has been applied but no success.
                            I have highlighted CMB_ on irc.

                              fattylewis' issue looks to have been caused by a different problem, openbgpd also seems to be able to trigger that PF_KEY error (even though in his case BGP wasn't doing anything, just running).

                              Arendtsen: /msged you on IRC.

                                Just noticed something new.
                                A reboot of the server (virtual on esxi) brings up the ipsec tunnels.
                                After about eight hours it's seems like they just appear up but there is no SADs or SPDs

                                  This sounds like the same issue as I am having here: https://forum.pfsense.org/index.php?topic=108706.0

                                  I am using the OpenBGPD package as well…

                                  Since I posted that I am no longer running the beta version but the issue still persists. I will give the patch linked earlier a go to see if it makes any difference for me, if anyone else has any suggested fixes happy to give them a go.

                                    After cmb removed openbgpd (i wasnt actually using it at the time) everything has been fine with my tunnels.

                                      Unfortunately I need OpenBGPD as I advertise prefixes that need to be routed over the IPSEC tunnels to the pfSense server. Its both too hard to keep track of which prefixes go where and much easier from a failover/traffic engineering point of view to not use it for my case. In this particular situation I also advertise the prefixes in the local office network to the pfSense server from the switches as there are quite a few different networks. I hope that there is a work around at some point, I would be happy to be a guinea pig for it.

                                        This is exactly why i am so glad i updated my home system before doing my office router…

                                        I guess best you can do is see what cmb says :(

                                          Hello!

                                          We have the same problem, applied the patch, however as we use OpenBGPD for AWS, ALL the IPSEC vpn's drop.

                                          The only way we fix it at the moment is to reboot the Firewall (this is not ideal).

                                          Any suggestions?

                                          Thanks

                                            Running into what appears to be the same issue.  I've installed the patch that CMB put up and I'm testing it out.  I don't IPsec a lot, but I'll see about trying to do some more in the next couple days to see if this remains fixed.  Luckily I have an OpenVPN connection that I use for other services that I can get back in and stop/start the IPSec service.  Below is a sanitized version of the error message:
