Abstract:
1. An authentication server comprising: a processor configured to receive a first authentication message, an authentication relay connected to a network transmits instead of a communication device, via the network, and execute network access authentication process on the communication device based on the first authentication message wherein, the communication device exists under the authentication relay and is not permitted to connect to the network before the network access authentication process on the communication device succeeds, and the first authentication message includes information for identifying the communication device, a source address of the first authentication message is an address of the authentication relay and a destination address of the first authentication message is an address of the authentication server; and to transmit a message, the message includes the server's address information and said information for identifying the communication device, to a predetermined one of the authentication relay and the communication device, when the network access authentication succeeds, wherein the communication device is permitted to connect to the network via the authentication relay after the network access authentication process succeeds, wherein when the network access authentication process succeeds on the communication device, the processor is configured to transmit instruction data to change a filtering setting to the authentication relay and another authentication relay belonging to same authentication domain as that of the authentication relay so as to permit that the communication device is connected to the network via the authentication relay and said other authentication relay, respectively.
