NAT  
 
Network Address Translation - an Internet standard that enables a LAN (local-area network) to use one set of IP addresses for internal traffic and a second set of addresses for external traffic. A NAT box located where the LAN meets the Internet makes all necessary IP address translations. A NAT can serve as a type of firewall hiding internal addresses from the Internet.
