H.323 Nat - Altigen AltiWare OE Version 4.6 Administration Manual

Board Configuration

H.323 NAT

The NAT router must support H.323. The router should know the H.323
protocol and be able to translate the private IP address into a public IP
address in H.323 packets. Normally, you should configure the router to
forward all the H.323 traffic to a specified IP address of H.323 endpoint
behind the NAT. This H.323 endpoint can be one of AltiWare's or the IP
phone. (The IP address of this H.323 endpoint is referred to as H323FWIP
- "H.323 Forward IP address.")
Private IP address
Only the private IP address is used in private network - the public router
will not route the packet that has a private IP address as its destination. (All
IP addresses beginning with 192.168.x.x are referred to as private IP
addresses.)
