Quote from: hollyjohn on July 06, 2026, 06:01:30 AMHello,You may need to configure gateway monitoring or a trigger that increases the CARP demotion level when the WAN goes down. Are you currently using dpinger for WAN monitoring?

I have two OPNsense servers, each with its own dedicated WAN connection, configured with CARP/HA. Failover works as expected if the primary server fails, becomes unresponsive, or is taken offline for maintenance.
The issue I'm seeing is that there is no failover when only the primary server's WAN connection goes down. The primary firewall remains the CARP master, so traffic doesn't switch to the secondary firewall even though its WAN connection is still up.
Can anyone point me in the right direction on what I should be checking or configuring to ensure the backup server takes over when the primary server loses WAN connectivity? Any suggestions would be greatly appreciated.

It was not an OPNsense problem.

(...) manually reboot the Opnsense boxThe update very likely was not complete. Do a health audit (System->Firmware->Status-Run an Audit), I bet it'll come up unclean.
