TANDBERG 6000 MXP user manual Advanced H.323 Settings, NAT Address

General Use

Advanced H.323 Settings

The Advanced H.323 Settings only have an effect if they are supported by your IP infrastructure.

NAT

NAT, Network Address Translation, is used when a PC and a video communication system are connected to a router with NAT support. NAT support in the video communication system enables proper exchange of audio/video data when connected to an external video communication system (when the IP traffic goes through a NAT router). When NAT is On, the NAT Server Address will be shown in the startup-menu: "My IP Address: 10.0.2.1".

On	The system will signal the configured "NAT Address" in place of its own IP-address
	within Q.931 and H.245.
Auto	The system will try to determine if the "NAT Address" or the real IP-address should
	be used within signaling. This is done to make it possible to place calls to endpoints
	on the LAN as well as endpoints on the WAN.

NAT Address

This must be the external/global IP-address to the router with NAT support. Packets sent to the router will then be routed to the system. In the router, the following ports must be routed to the system’s IP-address:

Port 1720

Port 5555-5560

Port 2326-2365

Please contact your TANDBERG representative for further information.

RSVP
Auto	Resource Reservation Protocol enables the systems to request the optimal amount
	of bandwidth for the duration of an IP videoconference.
Off	Resource Reservation Protocol is switched off.
