Easy Setup Profile configuration
The screen below is an example. Depending on the type of router you are using, fields displayed in this screen

The Local WAN IP Address is used to configure a NAT public address range consisting of the Local WAN IP
Address and all its por ts. The public address map list is named Easy-PAT List and the por t map list is named
Easy-Ser vers.
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
Binding Map Lists and Ser ver 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 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.
