Overview
NAT (Network Address Translation) is a means of mapping one or more IP addresses and/or IP ser vice por ts
into different values.
This
mapping
ser ves two functions:
•
It allows the addresses of many computers on a LAN to be represented to the public Internet by only one or
a few addresses, saving you money.
•
It can be used as a security feature by obscuring the true addresses of impor tant machines from potential
hackers on the Internet.
To help you understand some of the concepts discussed here, it may be helpful to introduce some NAT
terminology.
The term
mapping
refers to rules that associate one or more private addresses on the Motorola Netopia
®
Router’s LAN to one or more public addresses on the Motorola Netopia
®
Router’s WAN inter face (typically the
Internet).
The terms
private
and
internal
refer to addresses on the Motorola Netopia
®
Router’s LAN. These addresses are
considered private because they are protected or obscured by NAT and cannot be directly accessed from the
WAN (or Internet) side of the Motorola Netopia
®
Router unless specifically configured other wise.
The terms
public
and
external
refer to the WAN (or Internet) side of the Motorola Netopia
®
Router.
