CARP Sync Problem



  • Dear All,

    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

    https://doc.pfsense.org/index.php/Versions_of_pfSense_and_FreeBSD

    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.
