If you choose to place your video conferencing systems in a private LAN, you must use NAT to
communicate with outside systems. This may include enabling static NAT on your system.
Static NAT
NAT enables communication between devices on your LAN that have private IP addresses and
devices that are accessed through a public IP network. Static NAT ensures that the same public
IP address always maps to a system’s private IP address so that data from the public network
intended for the private system can be routed to the system reliably. If you are using static NAT
to associate a public IP address with the private IP address of your system, you must configure
your system to work with your static NAT server.
Note
Static NAT feature parameters on the system are described below:

If H.460 firewall traversal is enabled on the system, the system will automatically ignore the static
NAT settings for H.323 calls. For more information on H.460 firewall traversal, refer to on
Enabling H.460 Support for H.323 Calls on page 135 .
