The NAT Configuration Screens

8.1 Overview

Use these screens to configure port forwarding and trigger ports for the WiMAX
Modem. You can also enable and disable SIP, FTP, and H.323 ALG.
Network Address Translation (NAT) maps a host's IP address within one network
to a different IP address in another network. For example, you can use a NAT
router to map one IP address from your ISP to multiple private IP addresses for
the devices in your home network.
