      Did anyone ever do do this successfully?

      Also, has anyone successfully done multi-wan failover with a sonicwall?

      I also do not know how to apply the patch mentioned except to manually make the changes which doesn't seem like the best idea.

          Ah, got it. So I guess there's no way to use mutiple gateways for the remote side except to use Dynamic DNS?

              Can this be done if one side of the VPN is not a pfSense? I am going to a Fortigate on Fiber in Atlanta with a pfSense in Michigan with Cable and DSL connections.

              Thanks!

                Did you ever get an answer on this? I have a similar scenario and before I bang my head against the wall just wanted to know if you got it working.

                    Hello guys,

                    I have the pfSense firewall 2.1.3 and need configure ipsec failover with sonicwall. I know that sonicwall have the option for add the second peer in the configuration ipsec vpn, very easy.

                    Do you configure failover ipsec vpn?

                        Hi,

                        I can help you with the tests, ok.    Do you have dyndns service like a noip.com ?

                          I have a watchguard firewall on one end with Muiltiwan when going from watchgaurd to watchguard it works fine.

                          I now want to connect the Muilti wan watchgaurd over Ipsec VPN to a pfsence box with one wan connection.

                          What setup needs to be done on the both sides to get this to work so the pfsence knows what remote peer to connect to .

                          Right now it works when the connection it dropped but it will not drop the connection and failover to the preferred peer.

                          Thanks

                            The patch is no longer needed. There is a checkbox to activate the behavior on 2.1 (System > Advanced, Misc tab, under IP Security)

                            I am sorry, I can not find the checkbox in 2.2.6-RELEASE (amd64), under (System > Advanced, Misc tab, under IP Security), there is:
                            "These settings have moved to VPN > IPsec on the Advanced Settings tab. "

                            And in (VPN > IPsec on the Advanced Settings tab.) none of the options seems to be related, there are just these sections:
                            IPsec Logging Levels
                            Unique IDs
                            IP Compression
                            Strict interface binding
                            Unencrypted payloads in IKEv1 Main Mode
                            Maximum MSS
                            Disable Cisco Extensions
                            Strict CRL Checking
                            Make before Break
                            Auto-exclude LAN address

                            However in documentation (https://doc.pfsense.org/index.php/Advanced_IPsec_Settings) is mentioned "Force IPsec Reload on Failover".

                            Or the checkbox disappeared because IPsec multi-wan failover is performed reliably and IPsec restart is not needed anymore?

                            Thank you

                              pfSense 2.2 and later uses a different IPsec daemon that no longer requires that setting.

                                Setup DynDNS, set to use a failover gateway group.
                                Setup IPsec to use the same failover gateway group.

                                I've done this and the DynDNS works fine, updating the IP as the interfaces go up and down. But the IPSEC config isn't getting updated unless I manually reload it. Did I miss anything?
                                ps: I'm using this group in a Mobile Ipsec, not site-to-site.

                                  I figured out what was wrong.

                                  I was testing this failover feature by "marking the gateway as down", right at the "System -> Routing -> Edit Gateway -> Force State".
                                  This causes the DDNS service to imediatly update your DDNS record, but not the IP in the IPSEC conf file. Now I tested the failover by using the "ifconfig emx down" command, and this time both DDNS (though with some minor delay when compared to the previous option) and IPSEC updated the IP according to the active gateway's IP.

                                  So, IPSEC doesn't update it's active gateway's IP when using the "mark this gateway as down" option. Is this working as intended?

                                    And, we still have the bug that I posted:

                                    IPSEC bound to WAN gateway group and Dynamic DNS doesn't to fail back tunnel to WAN on DDNS update
                                    https://redmine.pfsense.org/issues/6370

                                    What can I do to get this issue looked at? It still an open bug, but, not confirmed nor assigned for fixing.

                                      Same here.
                                      Got a fast but unstable Vodafone cable Link (primary) and a slow but solid Telekom ADSL (backup).
                                      Last night, the cable link went down and up again several times. Due to the setting "enable default gateway switching" my servers were still reachable via a DynDns, but my site2site Ipsec tunnel (to DR Location) would use the wrong IP even after DynDns being updated.
                                      The tunnel was still shown as active in the morning, but no traffic was passing. Using the Restart button to restart IPSec did NOT solve the Problem, manually stopping and starting IPsec again DOES solve the problem…

                                      Had the same behaviour several times before...

                                      BTW: using latest 2.3.1_5

                                      @Steven Perreau: Did you also post a Bug report on Github?  Is this necessary / useful / recommended? I don't know which platform ist used by the Developers...

                                        I was working on a dual-WAN system yesterday where one of the links was flapping.  Had the exact same problem. Scratched my head for a while before trying what you did (completely stopping and then afterwards starting the Ipsec service)

                                          Not yet. That's really all there is to it though.

                                          Setup DynDNS, set to use a failover gateway group.
                                          Setup IPsec to use the same failover gateway group.
                                          Set the other end to use the dyndns host as the peer address.

                                          Sorry but i don't have DynDNS access to make the setup because both firewall are in my internal network(no internet access), so exist  another way to work ipsec  over multi-wan failover
                                          sorry about my English

                                            No, Dynamic DNS is the only viable way at the moment.

                                            Use an internal dynamic DNS server then. Setup BIND somewhere with an RFC2136 dynamic zone and have the other firewall use it to resolve hosts for a private domain.

                                            That's all out of scope for this thread/board though.
