You should probably better contact the firewall vendor to request a fix
to _their_ problem. I know this is not an answer to your delivery
problems, but we should try to ask for fixing broken servers/firewalls
before tricking/patching our perfectly configured servers. After all the
problem is in the firewall, not in your server.
