PROBLEM TO BE SOLVED: To solve the problem in which for reducing the load applied to an authentication server of a communication system, information for a regular terminal must be preliminarily registered, and management is complicated when a terminal or the like is added. SOLUTION: The system comprises the main terminal provided between an authentication server for authenticating a sub-terminal by exchange of authentication data and the sub-terminal. The main terminal comprises a connection control unit 14 controlling connection of a physical layer with the sub-terminal; an authentication state table 29 storing at least ID information of the sub-terminal contained in authentication request data which the sub-terminal transmits to the authentication server when requesting authentication; and an authentication state control unit 13 which makes the authentication control unit 14 cut the connection of the physical layer with the sub-terminal when an authentication result contained in authentication answer data the authentication server transmits to the sub-terminal in response to the authentication request data transferred to the authentication server shows that the sub-terminal corresponding to the ID information stored in the authentication state table 29 is an unpermitted terminal.
