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 an endpoint’s private IP address so that data from the public network
intended for the private endpoint can be routed to the endpoint reliably. If you are using static
NAT to associate a public IP address with the private IP address of your endpoint, you must
configure your endpoint to work with your static NAT server.
Note
Static NAT feature parameters on the endpoint are described below:

Web User Interface
If H.460 firewall traversal is enabled on the endpoint, the endpoint 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 142 .
