NAT allows a single device, such as a router, to act as an agent between the Internet
(or
"Public
Network") and a local (or "Private") network. This means that only a single, unique
IP address is required to represent an entire group of computer.
It works like your street address – as a way to find out exactly where you are
delivering information to you.
NAT serves three purposes:
1. Provide security by hiding internal IP address. Acts like firewall
2. Enable a company to access internal IP addresses. Internal IP addresses that are
only available within the company will not conflict with public IP.
3. Allow a company to combine multiple ISDN connections into a single internet
connection.
