IP Setup and Network Address Translation 9-3Using Network Address TranslationThe following procedure describes how to use Network Address Translation.1. Pick a network number for your local network (referred to as the internal network). This can be any IPaddress range you want. The Netopia R7100 SDSL Router has a default IP address of 192.168.1.1. Youmay choose to change this address to match a pre-existing addressing scheme. For this example, we willuse 10.0.0.0.Note: The outside world (the external network) will not see this network number.2. Using the internal network number, assign addresses to the local nodes on your LAN. For example, youcould assign 10.0.0.1 to your Netopia R7100 10.0.0.2 to a node running as a World Wide Web server 10.0.0.3 to an FTP server 10.0.0.4 to a Windows NT PC 10.0.0.5 to a Windows 95 PCNote: See “Associating port numbers with nodes” on page 9-6.3.
