IP Setup and Network Address Translation 10-3

Using Network Address Translation

The 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 IP address range you want. The Netopia R7200 SDSL Router has a default IP address of 192.168.1.1. You may choose to change this address to match a pre-existing addressing scheme. For this example, we will use 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, you could assign

■10.0.0.1 to your Netopia R7200

■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 PC

Note: See “Associating port numbers with nodes” on page 10-6.

3.In the connection profile, toggle Address Translation Enabled to Yes or No (Yes to enable NAT) and press Return.

The Easy Setup connection profile is accessible by using either of the following two approaches:

■From the Easy Setup menu in the Main Menu screen, select the next screen, Connection Profile 1: Easy Setup Profile. The screen shown below appears.
