Patent Images
1. An information appliance comprising:
- a P2P connection section that establishes a P2P (peer to peer) connection to a mobile terminal on an IP (internet protocol) communication network via a router;
a router operation section that changes setting information of a routing table of the router; and
an attack detection section that detects a network attack,wherein the router operation section changes the setting information of the routing table of the router to close a P2P connection port of the router in response to the detection of the network attack by the attack detection section.

Abstract
A mobile terminal and a home-use information product capable of retaining the security even under a network attack, while achieving P2P connection. When detecting a network attack, a home-use information product (104) notifies a mobile terminal (102) of the network attack. When receiving the notification, the mobile terminal (102) closes the port of a P2P connection part (121), requests the home-use information product (104) to close its port, and causes the home-use information product (104) to close the P2P connection port of a NAT router (103).
