Abstract

A system includes a first device for receiving a datagram from a public network whose destination is specified by a globally unique Internet Protocol (IP) address and for performing network address translation of said globally unique IP address to a non-globally unique IP address in a private network; and a second device for routing said datagram to a user device connected to the second device wherein said user device includes the destination specified by said non-globally unique IP address and for performing basic network address translation to said non-globally unique IP address to said corresponding globally unique IP address.
