Description: Network Address Translation (NAT) is a method by which Internet Protocol (IP) addresses are mapped from one realm to another, in an attempt to provide transparent routing to hosts. Traditionally, NAT devices are used to connect an isolated address realm with private unregistered addresses to an external realm with globally unique registered addresses.
