CARP Double Master (Previously 100% Stable Setup)
-
Today we had an odd incident with our HA setup of firewalls, both are Netgate 1541 Max units and have been running fine for about 5 years, no recent configuration changes have taken affect (by recent I mean we updated to 25.07.1 shortly after it came out, nothing since then, since I know "recent" is relative).
For some reason the backup unit took the WAN connection as Master, while all other interfaces stayed as Backup, but the primary was also Master.
Again only for the WAN connection, and a reboot solved this, but I was still hoping to get some info/pointers from anyone on figuring out why this might have happened in the first place.
I did a pcap on it before rebooting and the VRRP advertisements were showing up on the backup/secondary firewall, so it wasn't an issue with the primary no longer sending out advertisements.
