1. Introduction

The ITG is a VoIP gateway integrated with a Network Address Translation (NAT) router. It is equipped with two IP interfaces, one for connecting to internal network (hereafter called LAN), the other for connecting to external network (hereafter called WAN). The ITG performs NAPT for host in LAN interface, allowing multiple hosts in the LAN interface to share a single IP address.

The ITG has a built-in command line interpreter and provides users a Command Line Interface (CLI). You can configure ITG by entering commands from the CLI.

You can access the CLI from a VT-100 terminal or terminal emulator connected through a Telnet session.
