Abstract
An object of the present invention is to more appropriately filter a packet from an external device. This object is achieved by: obtaining address information of the external device from the packet; judging whether or not the address information of the external device has been registered as filter information; extracting, when it is judged that the address information has not been registered, device discrimination information of the external device from the address information of the external device; judging whether or not address information having the same device discrimination information as the extracted device discrimination information has been registered as the filter information; and registering, when it is judged that the address information having the same device discrimination information has been registered, the address information of the external device as the filter information.
