We have been suffering an issue to do with Checkpoint, Cisco GRE tunnels and MTU size for a number of months now, and I thought it might be worth posting a description of our problem on this list in case someone is able to help. We feel that we have exhausted most avenues of trying to troubleshoot this issue.
You might try the solution SK14995 of Check Point's knowledge base. It suggest to set "fw_clamp_tcp_mss = true" in objects_5_0.C in conjunction with tuning the MTU size of the Interface in question.
