Abstract

A method and apparatus for communicating data units (e.g., Internet Protocol or IP packets) between devices (22, 24, 36, 49) on one or more networks includes storing address and/or port translation information, and receiving a data unit having a source address and port and a destination address and port. Both the source and destination addresses and/or ports are translated, with the data unit containing the translated source and destination addresses and/or ports transmitted to a destination.
