Abstract: Provided is a gateway device connected to a bus used in communication by multiple electronic control units (ECUs) in a vehicle network system, which minimizes adverse effects on the vehicle network and which may use a determination technique taking some amount of time to determine whether or not a received frame is appropriate. A gateway 300a that forwards frames between a bus 200a and a bus 200b includes a receiving unit that receives a first frame, and a transmitting unit that, when a first frame transmitted by an ECU 100a, for example, is received from the bus 200a by the receiving unit, includes, in a second frame including information based on content of the first frame, first control information related to a restriction on processing after reception of the second frame, and transmits the second frame to the bus 200b.
