The Local WAN IP Address is used to configure a NAT public address range consisting of the Local WAN IP Address and all its ports. The public address map list is named Easy-PAT List and the port map list is named Easy-Servers.

The two map lists, Easy-PAT List and Easy-Servers, 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 Binding Map Lists and Server Lists on page 9-20.

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

Server Lists and Dynamic 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 server lists, a list of internal services 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 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.
