CARP Sync Problem
I have 2 pfSense VM.
Master version: 2.3.4
Backup version: 2.3.2
I configured CARP. Everything seems is ok. But master didn`t replicate its configuration to backup.
HA, VIP, Firewall Rules configured. Two VM ping each other.
But when i go to Backup server i see this. See attachment.
The configuration versions of pfSense must be identical on both units.
It can't synchronize from 2.3.4 to 2.3.2 because they have different configuration formats
2.3.4 is revision 15.8, 2.3.2 is 15.5. Attempting to synchronize that could cause a bad configuration to be loaded on the backup unit.
Upgrade both to 2.3.5-p1 (or preferably 2.4.2-p1) and try again.
