PROBLEM TO BE SOLVED: To prevent an illegal invader pretending to be a qualified user from gaining access to an application for an internal network from an external network and prevent slow-down of a main server due to a large amount of communication. SOLUTION: An LAN adaptor is provided with identification information, the LAN adaptor adds identification information to received data and transfers the same to the server. The server controls so that the received data through a specified LAN adaptor refuses the connection with the application for the internal network. The storage area amount for data communication to be used by the LAN adaptor is informed from the server, and when the LAN adaptor receives the received data exceeding the informed storage area amount, it is controlled not to transfer the data to the server, thereby preventing slow-down of the other services such as the application for the internal network due to exhaustion of storage area for the data communication.
