While I'm usually runnning Linux firewall, I once had the pleasure with Netscreen. They do some kind of DOS protection which may make it unusable to run servers behind. You have to remove those rules to make things work as expected. I don't remember in detail what was needed on the Netscreen, but you may find out yourself. At least I agree with you that you may have found the root of your problems.
