NAT

NAT is a method of mapping one or more IP addresses and/or services ports into different
specified services, where NAT stands for Network Address Translation. It allows the
internal IP addresses of many computers on a Local Area Network (LAN) to be translated
to one public address, saving users' cost. It also plays a security role by obscuring the true
IP addresses of important machines form potential hackers on the Internet. For
convenience, we called a router having the NAT facility as a NAT-enabled router.
