An information processing device that causes a router to open a new communication port and permits an active access from a terminal when the terminal connected to an outer network requires is provided. A multi function device (100) (an information processing device) accesses to a POP server (56) and acquires a mail. In a case where the mail from an outer terminal (60) describes an access request, the multi function device (100) transmits to a router (52) a port-open-command that requests the router (52) to open a new communication port. The multi function device (100) transmits to the outer terminal (60) a port identifier of the new communication port that was opened by the router (52). The outer terminal (60) transmits data to the multi function device (100) with the received port identifier designated therein. The multi function device (100), triggered by the mail from the outer terminal (60), can cause the router (52) to open a new communication port that permits an active access from the outer terminal (60). Therefore, the outer terminal (60) can actively access to the multi function device (100) through the new communication port that has been opened by the multi function device (100). |
