<p><P>PROBLEM TO BE SOLVED: To provide 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. <P>SOLUTION: 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 has been 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. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
