To provide. Further, another object of the present invention is to limit the communication network connection system to which the public network connection system can be connected, thereby limiting the services that users can receive, or reducing the risk of computer virus intrusion and information leakage. It is an object of the present invention to provide a communication network access point system capable of reducing the number.
