Avaya 1600 manual Configuring the NAT port range

Configuring the NAT port range

Under normal circumstances, the port range default setting is adequate. However, if you interact with multiple-player IP games or video conferencing, you need to configure the port range setting.

To multiplex several connections to a single destination, the PARTNER ACS 1600 DSL module assigns all packets unique port numbers. Each IP packet starts with a header that contain the source and destination addresses, as well as two port numbers. The addresses specify the two routers at each end, while the two port numbers ensure the unique identification of each router pair.

When the PARTNER ACS 1600 DSL module sends TCP or UDP connection from a local port to an Internet port, it changes the sent IP address to the address of the Internet port. Similarly, it changes the TCP or UDP connection port number to a unique value within the NAT port range.

The NAT port range must not include any ports that use applications such as HTTP, TFTP and so on.

To configure the NAT port range:

1.On the Main Menu, select Configure NAT.

The NAT Configuration Menu displays.
