Bug #16544
closed
During WAN failover event, HAproxy frontend IPs are not transferred from the primary to the secondary pfSense HAproxy service
0%
Description
Configuration synchronization via XMLRPC is enabled. Configuration appears to be syncing, but failover of the frontend LAN IPs does not occur when the primary pfSense firewall goes offline. Secondary always shows an error pertaining to multiple frontends using the same undefined IP, and HAproxy does not function when the secondary is the active firewall. This causes a production outage.

Unfortunately I cannot run beta software as this is for a production environment. It seems it'll be in my company's best interest to move to HAproxy on a standalone pair of systems for future stability, so will be taking that route.
Hello,
25.11 is now in stable. Let us know if you can still reproduce this issue on the latest stable build.
