A device authentication unit authenticates a wireless LAN terminal in response to a request from a connection control unit, and requests the connection control unit to send a device authentication result to a wireless LAN terminal. The connection control unit executes a procedure for device authentication between a wireless LAN control unit and the device authentication unit, and monitors a packet transmitted between the wireless LAN control unit and a bridge control unit. The connection control unit determines whether or not a wireless LAN terminal is already authenticated, on the basis of the MAC (Media Access Control) address assigned to the terminal, thereby transferring only acceptable packets, and braking off the other packets.
