      @viragomann said in IPsec site to site dropping every 49-55 minutes:

      I have 28800 in p1 and 3600 in p2.

      I now have this set AND i went ahead and changed my phase 2 encryption to AES ... 256 bit ... SHA256 to match the Phase 1 encryption.

      Let's see what happens in 49-55 minutes!

      Thanks again!

        @viragomann So I just caught it right as it happened, and here are the log files. it looks like I lost site to site ping at 18:31:19 (earliest reported at Site B) and it came back at 18:32:03 (also Site B). Not down for long, but that does cause the drop in phones and issues across the sites.

        Any ideas?

        Here are the logs:

        Site A (18:31:20 hours to 18:32:02) and here are the ipsec logs (Newest to Oldest)

          So I found this setting that says "Make before Break," and I am wondering if that is the issue I am running into as it is breaking, then renegotiating then reconnecting, which would cause that issue. So it is now enabled; however, my latency went way up for some reason.

          My Phase One is:
          Life Time: 28800
          Rekey Time: 25920
          Reauth Time: 0
          Rand Time: 2880

          Phy Phase Two(s) are:
          Life Time: 4000
          ReKey Time: 3600
          Rand Time: 400

          Now, in their instructions; it shows that these should match site-to-site. Is this the case in your experience?

            It looks like this triggers a bunch of deleting of CHILD_SA's which seems to break the tunnel.

            What are the actual P2 subnets on each side?

            You might also be experiencing "leakage" during the rekeying, where during the brief interruption, the IPsec routes disappear from the routing table and so pfSense sends the traffic out the WAN interfaces. This causes states to become established which causes it to continue to try sending traffic out the WAN until the state expires.

            You can prevent this by creating a floating rule, with source interface WAN, destination <VPN subnet>, direction Out, action Block.
            This causes any attempts to send the VPN subnet traffic out the WAN to be blocked (dropped) and prevents an outbound state from being established on the WAN interface.

              @andrew_cb Thank you very much for the reply.

              Site A Phase 2 remote subnets
              P2-1:

              • Local Subnet: LAN Subnet (10.1.0.0/16
              • Remote Subnet: 10.2.0.0/16 (Site B LAN Subnet)
                P2-2:
              • Local Subnet: LAN Subnet (10.1.0.0/16)
              • Remote Subnet: 10.0.1.0/24 (for a road warrior open VPN connection at site B)

              Site B Phase 2 remote subnets
              P2-1

              • Local Subnet: LAN Subnet (10.2.0.0/16)
              • Remote Subnet 10.1.0.0/16 (Site A LAN Subnet)
                P2-2
              • Local Subnet: 10.0.1.0/24 (for a road warrior open VPN connection at site B)
              • Remote Subnet: 10.1.0.0/16 (Site A LAN Subnet)

              I thought I turned on "Make before break" last night, but I apparently was so tired I forgot to apply the changes and restart the VPN. I just did this now, show hopefully this might fix the issue; however, I am going to also implement your suggestion of the floating rule.

              In fact I'm looking at this now, but I do have a quick question about the config:

              Action => Block
              Interface ... Should this be WAN or IPsec?
              Direction => out
              Address Family => IPv4
              Protocol => Any
              Source ... should be WAN Address? I'm running HA so I have VIP, should it be the VIP Address? or should I do one for WAN and a separate for VIP?
              Destination ... I'm going to need 1 for both remote subnets on Site A and just the Site B subnet

              How close am I on this configuration?

                Well, I was hoping the "Make before break" setting would have resulted this issue, yet at 58 minutes it trimmed out for about 45 seconds again.

                  @andrew_cb Just looking at this again as I know there is a time difference, but shouldn't this be the configuration if we do not want the IPsec traffic to go out the WAN?

                  Action => Block
                  Interface => IPsec
                  Direction => out
                  Address Family => IPv4
                  Protocol => Any
                  Source => LAN
                  Destination => WAN RTR1 / WAN RTR2 / VIP WAN

                  Maybe i'm thinking about this wrong, but this would keep IPsec traffic from the lan going out over the wan, or am I wrong?

                  PS, the system is still dropping for about 40-50 seconds every 55-ish minutes. I'm going to get the logs again shortly.

                    Here are the updated logs for the timeout session that just happened:

                    I am wondering if i should change the ReKey on the Phase2 as it is happening at 55 minutes on a 60 expiration and a 3-4 minute random.

                    I started getting ping timeouts at 14:59:02 and service return at 3:00:03

                      Same thing just happened again. 54 minutes after the last one it went down for roughly 45 seconds.

                        @andrew_cb Just looking at this again as I know there is a time difference, but shouldn't this be the configuration if we do not want the IPsec traffic to go out the WAN?

                        Action => Block
                        Interface => IPsec
                        Direction => out
                        Address Family => IPv4
                        Protocol => Any
                        Source => LAN
                        Destination => WAN RTR1 / WAN RTR2 / VIP WAN

                        Maybe i'm thinking about this wrong, but this would keep IPsec traffic from the lan going out over the wan, or am I wrong?

                        PS, the system is still dropping for about 40-50 seconds every 55-ish minutes. I'm going to get the logs again shortly.

                        If the remote subnets are being removed from the firewall's routing table then they are sent out the default route (i.e. 0.0.0.0 / WAN).
                        When traffic is sent out the WAN, it gets NAT'ed so that the source address is now the WAN IP, and then it is sent out the WAN interface.
                        A state is created on the WAN interface with the source address being the WAN IP (due to NAT) and the destination will be the remote VPN subnet.
                        This state will persist and cause the firewall to keep sending traffic destined for the remote VPN subnet out the WAN instead.

                        Eventually a program will timeout and stop transmitting. When the program tries again, it usually uses a different source port, which causes a new session to be created on the firewall. If the VPN's P2 are established, then the new traffic is correctly sent over the VPN tunnel.

                        The floating block rule is set on the WAN interface with source of WAN Address because NAT is performed before the firewall rules are processed.

                          @andrew_cb Okay, I think i understand now.

                          This means that the rule should look as follows:

                          Action => Block
                          Interface => WAN/WAN VIP
                          Direction => out
                          Address Family => IPv4
                          Protocol => Any
                          Source => WAN/WAN VIP
                          Destination => For Site A = Site B Subnets && for Site B = Site A Subnets

                          Let me know if I've got it right this time!

                          Thanks again,

                            @andrew_cb well, I have the rules as this one setup above, and it still timed out. Maybe I just need to set P2 to timeout at like 24 hours and then apply it and reboot at like 6:00 AM that way it will take it months to timeout during the working period.

                            It just seems odd that I have "Make before break" enabled, yet it isn't doing that.

                            Thinking about it, I have it set to WAN SUBNETS as the source as this uses CARP and VIP Ip address. Should I change it to just the "IP address" that is the VIP IP?

                              So i have my firewall rule to block on the WAN VIP address to see if it will stop that 45-50 second down time.

                              I also performed a test and setup my tunnel times as follows:

                              Phase 1:

                              • Lifetime 604,800 (7 days/168 hours)
                              • ReKey 604,200 (10 minutes less than lifetime)
                              • ReAuth 160 (2 minutes) (This might need to be 604,640)
                              • Rand Time 60 (1 minute)

                              Phase 2:

                              • 86,400 (1 day/24 hours)
                              • 85,800 (10 minutes less than lifetime)
                              • 60 (1 minute)

                              The results were disastrously. The tunnels were resting every 45-50 seconds and it was creating multiple connection visible in the ipsec status.

                              I reset everything back to the original mentioned above, but we're still timing out at the 55-ish minute mark, which is not good during business hours as phone calls and app connections are failing.

                              I do have a question. If i am using make before break, do i still need "Phase One Child SA Close Action" to be restart? Shouldn't it be close?

                              Any thoughts? I'm about ready to move on and try wireguard.

                                I did a little checking and the tunnel is going down every 53 minutes 30 seconds (give or take a second).

                                Then it is down for approximately 38 - 40 seconds.

                                This is super strange that I have make before break enabled, but it is still doing this.

                                Thanks in advance!

                                  We are running CARP and both sites are running identical hardware (Dell R620) with pfSense 24.11-RELEASE.

                                  A couple of things.

                                  1. Are you using the WAN CARP address to establish your IPsec tunnels?
                                  2. For your IPsec tunnels. Do you have gateway monitoring enabled?
                                  3. Have you enabled DPD ?

                                    @michmoor Thanks for the reply!

                                    1.) I am using the shared Virtual IP address so that way if RTR1 goes down RTR2 can provide the services.

                                    2.) I need to find that feature. inside Phase One there is a "Gateway Duplicate" that is disabled. Do you know where the "gateway monitoring enabled" is by any chance?

                                    3.) DPD is enabled in Phase One on both side of the tunnel.

                                    Thanks again!

                                        @michmoor I found the Gateway monitoring setting in: System > Routing > Gateways > Edit

                                        Gateway Monitoring - Disable Gateway Monitoring
                                        This will consider this gateway as always being up.

                                        Is this what you are talking about? Reading it, without it being checked gateway monitoring is enabled.

                                        I went ahead and disabled the "Gateway Monitoring" and "Gateway Action."

                                        Thanks again,

                                          I care more about Gateway Action. If that's set, lets unselect for now. Im assuming you are NOT in a multi-wan configuration

                                          What that does is that if there is an issue with your gateway monitor IP (packet loss, jitter) this will bring down the IPsec connection in your case.

                                            Correct, we are in a single WAN configuration. They were both "enabled" or "un-checked" and i went ahead and "checked" them on both sites
