The two map lists, Easy-PAT List and Easy-Ser vers, are created by default and NAT configuration becomes 
effective.This will map all your private addresses (0.0.0.0 through 255.255.255.255) to your public address. 
These map lists are bound to the Easy Setup Profile. See 

This is all you need to do if you want to continue to use a single PAT, or 1-to-many, NAT configuration.

You use the advanced NAT feature sets by first defining a series of mapping rules and then grouping them into 
a list. There are two kinds of lists -- map lists, made up of dynamic, PAT and static mapping rules, and ser ver 
lists, a list of internal ser vices to be presented to the external world. Creating these lists is a four-step process:

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 ser ver 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.

In order to configure the Router to make ser vers on your LAN visible to the Internet, you use advanced features
