Network Address Translation (NAT)

NAT Scenarios

117237-C Rev. A
Network Address Translation (NAT) is a method for translating
an internal IP address or network into a single globally unique IP
address.
There are several benefits for using NAT, internal address re-use;
use of unregistered addresses; the ability to hide internal network
addresses; not needing to re-address the internal network when
connecting to the internet or a corporate network.
The most important benefit of NAT for Nautica routers is the
ability for the router to be assigned an IP address by a service
provider, without needing to reconfigure the network behind the
router.
For information on how to configure NAT on a Nautica router,
refer to Chapter 14.
There are three scenarios in which NAT can be used on a Nautica
router.
1. A single PC connected to a Nautica router which connects to
an internet provider.
