PROBLEM TO BE SOLVED: To provide a technique that can move an external terminal which was once authenticated between network relay devices without performing authentication processing again.SOLUTION: When an authentication response is transmitted from an authentication server 40 to a first member device 22b-2 (S96), the first member device 22b-2 performs communication permission processing (S98). When the first member device 22b-2 completes the communication permission processing, it transmits login terminal information to a master device 22a and a second member device 22c-2 (S100, S102), and the master device 22a and the second member device 22c-2 perform communication permission processing on the basis of the login terminal information (S104, S106). For this reason, if an external terminal 30 moves from the first member device 22b-2 to the second member device 22c-2 (S114), the second member device 22c-2 has already performed the communication permission processing (S106), and does not need login again, and the external terminal 30 can continue to maintain a login state. |
