PROBLEM TO BE SOLVED: To achieve filtering based on the same policy when a user or a terminal is the same by performing the identification of a user between networks or the coordination of a filtering policy.SOLUTION: When a first network receives terminal information from a terminal, the first network transmits the terminal information to a second terminal to request the authentication of the terminal, and when the terminal is authenticated by the second network, the first network requests a filtering policy to the second network, and the second network transmits the filtering policy stored in association with the terminal information in policy storage means to the first network. The first network determines whether to pass or abandon a packet received from the terminal on the basis of the filtering policy acquired from the second network, and sends the packet determined to be passed to an external network. |
