Multiple Network Address Translation 11-7

1.Define the public range of addresses that external computers should use to get to the NAT internal machines. These are the addresses that someone on the Internet would see.

2.Create a List name that will act as a rule or server holder.

3.Create a map or rule that specifies the internal range of NATed addresses and the external range they are to be associated with.

4.Associate the Map or Server List to your WAN interface via a Connection Profile or the Default Profile.

The three NAT features all operate completely independently of each other, although they can be used simultaneously on the same Connection Profile.

You can configure a simple 1-to-many PAT (often referred to simply as NAT) mapping using Easy Setup. More complex setups require configuration using the Network Address Translation item on the IP Setup screen.

An example MultiNAT configuration at the end of this chapter describes some applications for these features. See the MultiNAT Configuration Example on page 11-28.

In order to configure the router to make servers on your LAN visible to the Internet, you use advanced features in the System Configuration screens, described in IP setup.
