CARP failover HA Sync-Slave pings Master but master doesn't ping slave



  • ******Hello Everyone,

    After successfully configuring Multi-WAN failover with a default gateway, I have hit a hurdle in Carp failover HA sync. I have configured dedicated interface in both the master and slave. The master ip address is 192.168.100.10/24 GW - 192.168.100.11/24(Slave ip). The slave ip address is 192.168.100.11/24 GW - 192.168.100.10(master ip).******



  • Have you managed to find a solution to this?

    It looks very similar to the problem I am having…

  • Your dedicated sync interface should not have a gateway set.
    Try adding allow all any any rules to the sync interfaces on both boxes. Backup unit won't get the allow rule from the master until it sync's once.

    y3- I replied on your thread, IMO it is not related to this thread.
