I have recently configured GLBP on my internet routers. It seems to work, but only for a short time. I have two Checkpoint routers in failover mode connected to a switch which is in turn connected to both of my Internet firewalls. Outbound traffic will load balance for a few hours, then switch to one of the two routers. Both routers are running 12.4(3E) IPBASEK9-M software. I have included the config statements for both routers (on the interfaces connected to our network) and the 'sho glpb' command from each router. Can anyone help?
