IP Setup
Motorola Netopia® Embedded Software Version 8.7.4 uses Internet Protocol (IP) to communicate both locally and with remote networks. This chapter shows you how to configure the gateway to route IP traffic. You also learn how to configure the gateway to serve IP addresses to hosts on your local network.
Motorola’s IP routing features Network Address Translation and IP address serving.
This section covers the following topics:
•“IP Setup” on page
•“RIP Options” on page
•“IP Address Serving” on page
•“More Address Serving Options” on page
•“DHCP Relay Agent” on page
•“Connection Profiles” on page
•“Multicast Forwarding” on page
Network Address Translation allows communication between the LAN connected to the Router and the Internet using a single (or a few) IP address(es) instead of a routed account with separate IP addresses for each computer on the network.
Network Address Translation also provides increased security by hiding the local IP addresses of the LAN connected to the Motorola Netopia® gateways from the outside world.
The setup is simpler, so ISPs typically offer Internet accounts supporting Network Address Translation at a significant cost savings.
For a detailed discussion of Network Address Translation, see Chapter 4,

IP Setup
The IP Setup options screen is where you configure the Ethernet side of the Router. The information you enter here controls how the gateway routes IP traffic.
Consult your network administrator or ISP to obtain the IP setup information (such as the Ethernet IP address, Ethernet subnet mask, default IP gateway, and Primary Domain Name Server IP address) you will need before changing any of the settings in this screen. Changes to these settings that you make in this screen will take effect only after the Motorola Netopia® device is reset.
