      Hi BlueKobold,

      we don't use OpenVPN on the PFSense. We only use IPSec.
      I don't know, why it will be displayed in the logs.

      The same is the gateway. We have a static public IP address
      and don't use a dyndns gateway.

        Oh ok thank you for providing this information, I was a little bit confused on this entries and was
        not really able what I should think on, thanks again for the clarification on this.

        I have another one for you, you where telling us that all was running fine for you and also
        the VPN connections before upgrading to a higher pfSense version, is this right? Perhaps,
        only perhaps I mean you or somebody was doing or making custom set up entries and after
        the update or upgrade was done all files was new written and this custom made settings were
        gone. And now the set up is not really fine working because the custom entries are not there.

        Could this be?

          No problem BlueKobold. Thanks for your response.

          Yes you are right. Before the upgrade to version 2.2.6,
          the PFSense was fine. We only have upgraded the PFSense
          to the latest version, but didn't changed anything in the configuration.

          After the upgrade the IPSec tunnel was disconnect every two
          days in the morning and the detection of the gateway had also
          a delay.

          Now i try to find out, if the latest version of PFSense has a bug
          or the modem of the ISP is defect. But i still think that the
          PFSense has a bug, because the IPSec issue did not occur
          in the versions before.

          Has anyone the same issue with IPSec in the latest version?

              Hi Max,

              Thanks for your reply.

              Do you have this issues also with version 2.2.6?
              If yes, it would be interesting to know how you
              got it fixed.

              Thanks and best regards,
              Niklas

                Hi FCNiklas,

                yes runnning  on 2.2.6. For me it's not a big problem because of using ipsec tunnel very less.

                I think the problem will gone if
                System: Gateways: Edit gateway
                Disable Gateway Monitoring  <- if not required because of fixed wan ip & no failover gateway

                or

                tuning the parameters "Advanced"

                regards

                max

                  Hi Max,

                  thanks for the information.

                  I have checked both PFSense firewalls and found out that
                  the option "Disable Gateway Monitoring" is not checked on
                  both Firewalls.

                  If i understand it correctly, the option only means that the
                  WAN IP will not be monitored again. That would be a workaround
                  to get no warnings in the system logs, but the issue would not fixed
                  by this.

                  What do you also mean with tuning the parameters "Advanced"?

                  Thanks for your help in advance.

                  Best regards,
                  Niklas

                    In the IPSec VPN settings is there enabled MSS clamping?

                      Hi BlueKobold,

                      no MSS clamping is not enabled on both PFSense Firewalls.

                      Has it something to do with the restart of the ipscec service?

                      It seems that the ipsec tunnel restarts more than before.

                      Here are the gateway logs again:

                      … and the general logs:

                      Its a very strange issue and it is inexplicable to me, what causes this issue,
                      because we haven't changed anything at the configuration of the IPSec settings.

                      Thanks in advance and best regards,
                      Niklas

                        Not installing NAT reflection rules for a port range > 500

                        Something is trying to get from the internal LAN through the WAN interface to connect in
                        the DMZ or LAN homed Servers and there are no rules for NAT reflection (Hairpin NAT)
                        could this be a problem too?

                        IPSEC: One or more IPsec tunnel endpoints has changed its IP. Refreshing.

                        Is there in the other LAN perhaps something likes an enabled DHCP Server that is giving
                        new IP addresses to servers or other devices that should be sorted more with static IP addresses?
