A system according to the present invention includes a first communication unit, a second communication unit, and an executing unit. The first communication unit is connected to a first network segment. The second communication unit is connected to a second network segment different from the first network segment, and receives a processing request, which requests to execute predetermined processing, from an apparatus via the second network segment and transmits the received processing request to the first communication unit. The executing unit executes the predetermined processing in response to the processing request received by the first communication unit.
