Abstract
A network system is constructed by: a first LAN system having first terminal equipment; a second LAN system having second terminal equipment; an intermediate network to connect the first and second LAN systems; first communication equipment to transfer a packet between the first LAN system and the intermediate network; and second communication equipment to transfer a packet between the second LAN system and the intermediate network. To transfer the packet from the first terminal equipment to the second terminal equipment, the first communication equipment converts an address showing a transmission destination of the packet transmitted from the first terminal equipment from an address defined on the first LAN system to an address defined on the intermediate network and transfers the converted address from the first LAN system to the intermediate network. The second communication equipment converts an address showing the transmission destination of the packet on the intermediate network from the address defined on the intermediate network to an address defined on the second LAN system and transfers the converted address from the intermediate network to the second LAN system.
