I have a version of the ClusterXL firewall, R77.20.

I have two sets of VoIP call systems. One is dialing through CheckPoint's internal network NAT. The other is dialing through the Internet. Strangely, I'm releasing two ports through the Internet's VOIP set. They are sip_up and sip_tcp. Then another set of VoIP can't dial!

My English is not good enough. Trouble
