      As I know, this lifetime is the idle time until the VPN will disconnect, so maybe when you upgraded, some of the traffic which flow through the VPN and keep it alive was stopped somehow.

      I'm not sure it this is the reason, and I have really no more ideas :)

        So far as i know, is there difference between the lifetime of Phase 1 and Phase 2.

        The lifetime in Phase 1 specifies the time period for the build of Phase 1.
        The lifetime in Phase 2 specifies the time period for the negotiated keys.

        I don't think that the problem comes from the traffic during the upgrade.
        The reconnect of the IPSec tunnel happens at first on location 1 and few
        hours later on location 2.

        In addition we haven't changed anything at the configuration on both firewalls.

        Does anyone has another idea to solve this issue?

        Currently we have only the possibility to wait for a new PFSense version and to
        hope that the issue was solved after upgrade. We also think about to downgrade
        the PFSense version again…

            Hi dboe732,

            our IPSec connection will reconnect automatically.

            Has nobody an idea to solve the issue?
            Or does someone know, when the next version will be published
            of the PFSense?

            Thanks in advance.

              The logs in your first post make it look like that happens after your WAN IP changes, or maybe just a WAN reconnection or renewal. Is that the case?

                Hi cmb,

                thanks for your response at first.

                We have static public ip addresses, which were not changed before.

                But i have found the following entries in our Gateway log on both PFSense firewalls:

                Feb 19 10:35:03 apinger: alarm canceled: GATEWAY(XX.XX.XX.XX) *** delay ***
                Feb 19 10:34:54 apinger: ALARM: GATEWAY(XX.XX.XX.XX) *** delay ***

                Feb 18 13:04:24 apinger: ALARM: GATEWAY(XX.XX.XX.XX) *** delay ***
                Feb 18 12:31:08 apinger: alarm canceled: GATEWAY(XX.XX.XX.XX) *** down ***
                Feb 18 12:30:03 apinger: ALARM: GATEWAY(XX.XX.XX.XX) *** down ***
                Feb 18 11:49:13 apinger: alarm canceled: GATEWAY(XX.XX.XX.XX) *** down ***
                Feb 18 11:18:36 apinger: ALARM: GATEWAY(XX.XX.XX.XX) *** down ***

                Could it be that the public ip addresses gets a new lease time at the provider, which caused
                the connection issues?

                Thanks in advance.

                  Sorry for jumping in here but something is not really clear to me, based on the logfiles and statements.

                  Feb 15 01:50:03    check_reload_status: Restarting OpenVPN tunnels/interfaces

                  So OpenVPN is used here in that case

                  Feb 15 01:50:03    check_reload_status: Restarting ipsec tunnels

                  Is OpenVPN using here an IPSec tunnel? In normal as I know it, you will be using OpenVPn or IPSec,
                  is this right or am I wrong with this?

                  Feb 15 01:50:03    check_reload_status: updating dyndns GATEWAY

                  And if a public static IP address is there in use, why then using DynDNS?

                  Sorry for this nOOp questions, but I am interested in this case really.

                    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,

                          also ipsec restart on a aping delay but comes up again

                          regards max

                            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

                                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:

                                    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?
