NAT configuration

You use the NAT feature sets by defining a series of remapping rules and then grouping them into a

list. There

are two kinds of lists --

Map Lists, made up of PAT and Static remapping 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:

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.

Create a List name that will act as a rule or ser ver holder.

Create an internal

map or rule that specifies the internal range of NATed addresses and how they are to be

aliased to the external range.

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.
