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 R7100 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 R7100
■
10.0.0.2 to a node running as a World Wide Web ser ver
■
10.0.0.3 to an FTP ser ver
■
10.0.0.4 to a Windows NT PC
■
10.0.0.5 to a Windows 95 PC
Note: See “Associating por t numbers with nodes” on page 9-6 .
3. In the connection profile, toggle Address Translation Enabled to Yes or No (Yes to enable NAT) and press
Return.
