IP Setup and Network Address Translation 9-3

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 R9100 Ethernet 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 R9100

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 9-5.

3.By default, Network Address Translation is enabled in the Netopia R9100. If you disabled it and now want to reenable it:

From the WAN Configuration menu in the Main Menu screen, select WAN (Wide Area Network) Setup. The WAN Ethernet Configuration screen appears.
