Forget to say that all NAT is setup correct and i have looked over this forum for any way to fix it :) BR

Yes, I think that makes the most sense. Change outbound NAT address from interface to CARP IP, then replace all primary IPs and create old primary as CARP VIP; apply all at once. Outage should be brief to none, then firewall B can be configured as backup.

Ok thanks, raised a freature request: https://redmine.pfsense.org/issues/10504

Thank you very much! That works, I'm most grateful.

Great. Thanks for the clarity.

I found the problem. I was using Hybrid NAT. After switching to Manual NAT and set all NAT Address to "CARP VIP" the problem is solved. ============== Update: Still not working... Getting Random Disconnect again... Update 2: If I Enable CARP Maintenance Mode, connect Fortinet SSLVPN, and disable CARP Maintenance Mode, the VPN will stay stable and no drop of connection.

How about a specific source IP address please?

Anyway you would consider making a Video tutorial of how you got this to work ? trying to achieve the same thing but video guide exists for those of us with a single dynamically assigned IP address

It was much better before browsers started lowering the life of the cert.. You could set the cert to be good for 10 years or something and never have to worry about it again.. Now they want to have longest life of 398 days - uggghhhh.. Glad all my certs grandfathered in, hehehe And good for the 10 some years ;) [image: 1587059128910-cert.jpg]

Look at /etc/rc.carpbackup and /etc/rc.carpmaster which get run when a VIP transitions to the state matching the name of the script.

Hi! I still very much have the same problem, is there anything I can provide to help get it fixed? Can anyone confirm/infirm what the following errors would cause, is my problem consistent with it?

It looks like every server which has a virtual IP has an issue of some kind after my Internet connection is reestablished.. There is a ticket open about this but it has not received any love in 2 years... See: https://redmine.pfsense.org/issues/8413 Thank you and have a nice day, Nick

Hooray! I got it working. Listening to music over VPN, through RDP, you only hear the sound cut out for maybe 0.5 seconds after a failover now. Was just an issue with the way I was testing my Public IP's offline. (Spoofing them internally + double nat lol)

@pete-s It works. You can choose to monitor a carp-interface, in which case haproxy will only run on the node that is 'master'.. Otherwise it will run on both, and perform health-checks from both. If you have stick-tables you want to keep synced youl need to have it running on both nodes, and the sync configuration could be a bit tricky (not really supported in the webgui though with some manual advanced texts there is almost nothing thats impossible ;) ..), Anyhow if you are only requiring that haproxy runs with the same config on both nodes that should be easy.. Just make sure to enable the 'config sync' checkbox only on the master node. p.s. in any case, all active connections will 'break'.. and need to be re-established when a failover happens.. it wont transfer the tcp-connection-states

@jimp @bbrendon hello guys, i have this issue !! do you have any suggestions ?? Exactly how you describe it... in the middle of the night , random hours, can happen also with low traffic and no traffic. How do you fix that ?
