Port Address Translation
Port Address Translation, also known as Network Port Address Translation (NPAT), is a feature of a Network Address Translation (NAT) device that translates not only IP addresses but also TCP or UDP ports between a host and port on an outside network to a host and port on an inside network. NPAT allows one single IP address to be used for many internal hosts. With NPAT one outside IP address can account for over 64000 inside hosts.
