Checkpoint Firewall

Do you know about any problem with checkpoint firewall and SGD4.2?I've a costumer with that firewall and he is disconnected quite often. Without firewall no problem. We check firewall log and see that some times it blocks traffic to our site... Any help?Thank You

Define "some times". A snip of the log with successful connections compared to unsuccessful connections would be helpful.
