Abstract: PROBLEM TO BE SOLVED: To switch a pass-through mode to a bridge mode in response to the connection secured to a mobile calculation device by peparing a packet path designation means, in addition to a means which redirects an information packet between a computer network and a fixed calculation device. SOLUTION: A mobile calculation device 14 (for example, notebook type personal computer(PC)) is connected to a fixed calculation device 12 (desktop- type PC) via a radio communication channel (infrared link) 16. Under such conditions, a system operates in a bridge mode and mutually redirects an information packet between the PC 14 and an Ethernet LAN 10 via the PC 12. When no PC 14 is connected to the system, the system operates in a pass- through mode and filters all non-broadcast communication message traffics received from the LAN 10 by an Ethernet adaptor, based on the network address of the PC 12 or a group address.
