Auto last hop enabled with Checkpoint firewall

The ICMP packet is going the right direction, The one thing is we are running GAIA on our Firewall cluster, I am wonder if someone has this same setup with ALH on and going thur a Checkpoint Firewall cluster with GAIA loaded. It seems like the F5 sends back the reply but the Checkpoint never sends it back to the Internal network. We had to turn ALH on to resolve a issue with Servers talking to the Virtual servers. Thanks for the replies Steve if you can think of anything else or if anyone in the community has this setup.
