Abstract
A gateway apparatus and method for routing packets between a local network and an outside network wherein a first converting unit converts a first header of each of packets transmitted from at least one of terminals of the local network to the outside network into a header assigned to the gateway apparatus. A conversion table stores entries referred to by the first converting unit in conversion. A second converting unit converts a second header of packets transmitted by the outside network to the local network into a header for the terminals of the local network. The gateway apparatus operates as a Layer 3 routing apparatus for the local network and operates as a terminal for the outside network.
