5.3 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 al lows 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 from potential hackers on the Internet. For convenience, we
called a router having the NAT facility as a NAT -enabled router.

local server.
