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
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 an internal
map
or rule that specifies the internal range of NATed addresses and how they are to be
aliased to the external range.
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.
See “MultiNAT Configuration Example” on page 10-24.
You configure the MultiNAT features through the console menu in three areas:
■ Easy Setup Profile, described on page 10-4.
■ IP setup, described on page 10-5.
■ IP profile parameters, described on page 10-18.
