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 

.

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:
