IP Setup

The Netopia 4752 uses Internet Protocol (IP) to communicate both locally and with remote networks. This chapter shows you how to configure the router to route IP traffic. You also learn how to configure the router to serve IP addresses to hosts on your local network.

Netopia’s IP routing features Network Address Translation, Virtual Private Networking (VPNs), and IP address serving.

This section covers the following topics:

■“IP Setup” on page 10-2

■“IP Address Serving” on page 10-10

■“More Address Serving Options” on page 10-17

■“DHCP Relay Agent” on page 10-23

■“Connection Profiles” on page 10-25

Network Address Translation allows communication between the LAN connected to the Netopia 4752 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 Netopia 4752 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 11, “Multiple Network Address Translation.”
