xConfiguration H323 NAT Mode
The firewall traversal technology creates a secure path through the firewall barrier, and enables 
proper exchange of audio/video data when connected to an external video conferencing 
system (when the IP traffic goes through a NAT router). NOTE: NAT does not work in conjunc-
tion with gatekeepers.
Requires user role: ADMIN
Default value: Off
USAGE:
xConfiguration H323 NAT Mode: 
Mode
where
Mode
: Auto/Off/On
Auto: The system will determine if the H323 NAT Address or the real IP address should 
be used in signaling. This makes it possible to place calls to endpoints on the LAN as 
well as endpoints on the WAN. If the H323 NAT Address is wrong or not set, the real IP 
address will be used.
Off: The system will signal the real IP address.
On: The system will signal the configured H323 NAT Address instead of its real IP 
address in Q.931 and H.245. The NAT server address will be shown in the startup-
menu as: "My IP Address: 10.0.2.1". If the H323 NAT Address is wrong or not set, H.323 
calls cannot be set up.
xConfiguration H323 NAT Address
Define the external/global IP address to the router with NAT support. Packets sent to the 
router will then be routed to the system. Note that NAT cannot be used when registered to a 
gatekeeper.
In the router, the following ports must be routed to the system's IP address: 
* Port 1720 
* Port 5555-6555 
* Port 2326-2487
Requires user role: ADMIN
Default value: ""
