PROBLEM TO BE SOLVED: To suppress degradation of a communication speed due to a communication load, and also offer enhanced security.SOLUTION: In a connection authentication system 100, a mobile terminal 10 which requests authentication performs authentication request via an authentication management server 20. As a fire wall 30 accepts access only from the specific authentication management server 20, the fire wall 30 does not directly perform authentication processing with the mobile terminal 10, but performs authentication of the mobile terminal 10 via the authentication management server 20. Then, when the fire wall 30 authorizes remote connection of the mobile terminal 10 as a result of the authentication, the fire wall 30 notifies the mobile terminal 10 of a port number of an external port to be opened. Thus, remote connection between the mobile terminal 10 and a client PC 50b can be established. |
