Setting up H.323 Traffic Forwarding for H.323 NAT

When you configure the H.323 NAT router, it can forward the IP traffic to
a specified private IP address based on the destination port in the TCP/IP
or UDP packets. When an H.323 endpoint is behind the H.323 NAT, you
should set up the forwarding to a private IP address of this H323 endpoint.
If this H.323 endpoint is AltiWare, the NAT router must be configured to
forward the following ports to the H.323 endpoint's private IP address:
