Introduction to Network Address Translation

This module discusses the features and functions of the Microsoft Network Address Translation (NAT) protocol.
When an organization decides to connect to the Internet, a primary consideration is how to provide Internet access for users on the private network while protecting private network resources. One way to provide this protection is to use private IP addresses on the internal network computers. In order to allow these computers to access the Internet, the private IP addresses must be translated into public IP addresses. This is the function of a NAT server.
Windows 2000 includes a NAT routing protocol with its Routing and Remote Access Service. NAT is an appropriate solution for networks that do not require extensive security for their outbound Internet requests.

At the end of this module, you will be able to:
  1. List the key features of the NAT protocol
  2. List the protocols that the NAT protocol does not support
  3. Describe how to design a functional NAT solution
  4. Identify the processes required to integrate NAT with other services in Windows 2000
  5. Describe how to select appropriate server options for a NAT solution
In the next lesson, you will learn about the key features of NAT.
