I have an FC11 box running LVS (1.2.5)/KeepaliveD (1.2.2) as a load balancer for HTTP, HTTPS, and DNS. The problem I'm running into is that the box does not appear to accept/recognize the GARP announcement from my separate Checkpoint firewall cluster. When the firewall cluster fails over, it sends a GARP to all systems on the LAN which maps the cluster's IP address to the MAC of the new member. When this occurs, all the systems except for the LVS load balancer will update their ARP tables as expected. The LVS load balancer continues to communicate with the cluster IP at the old MAC which pretty much cuts off communication.
If I go in and manually update the arp tables, everything works again, but since the firewall does a quick failover whenever I push policy out to it - I have to quickly reset the cluster to its original primary/secondary order to avoid any outages. I'm at a bit of a loss right now as to what I must change on the load balancer so it will accept the GARP from the firewall, can anyone please point me in the right direction? On my real servers I had to set up dummy interfaces so that they could rx/tx with the virtual IP's on the balancer, does something similar need to be done so the load balancer can communicate properly with the firewall cluster?
