Auto last hop enabled with Checkpoint firewall

Yes the servers are on the same subnet as the F5's The gateway for the subnets themsleves are the checkpoint, we have a special subnet for the Virtual addresses, that when a transaction comes in it goes thru the checkpoints, to the F5 and than to the server. We do have default routes setup for all the transit networks back to the checkpoint. Before we turned ALH on to fix a issue we were able to ping the Virtual address the tcpdumps do show the ICMP packet talking between the devices. I agree that with ALH on the issue is related to the way Checkpoint uses the mac address.
