Abstract
A network repeater apparatus connected to a plurality of networks is provided which includes a VLAN tag addition section (15) or a VLAN tag rewrite section (17) that performs prescribed VLAN tag processing with respect to a communication packet based on prescribed information of the communication packet when the communication packet is input from any one among a plurality of networks, an address translation section (16) that translates a source address of the communication packet based on the prescribed information, and an input and output section (11) that outputs to a prescribed virtual network a communication packet which has been subjected to at least either one of processing by the VLAN tag addition section (15) or the VLAN tag rewrite section (17) or address translation by the address translation part (16), whereby access can be made to a common device while ensuring security between the networks.
