Abstract: Provided are an information processing system, a tunnel communication device, a tunnel communication method, and a program that can make a communication between plural information processing devices belonging to different LANs without a user's making a complex setup. In the information processing system, a first tunnel communication unit encapsulates a packet from a first information processing device, transmits the encapsulated packet through a path of a P2P communication, and decapsulates the packet transmitted from a second tunnel communication device through the path of the P2P communication. A second tunnel communication unit encapsulates the packet transmitted from the second information processing device, transmits the encapsulated packet through the path of the P2P communication, and decapsulates the packet transmitted from the first tunnel communication device through the path of the P2P communication.

Abstract: Provided is an information processing system and the like that can make a communication between plural information processing devices belonging to different LANs. A first tunnel communication device includes a first address correlating information memory unit that stores information for correlating an address in a first LAN with an address in a second LAN, a first address translating unit that translates an address of a packet on the basis of the correlating information, a first P2P communication setup unit that sets up a P2P communication with a device as a destination, and a first tunnel communication unit that makes a tunnel communication through a path of a P2P communication. The packet transmitted from a first information processing device is translated in address, is encapsulated, and is then transmitted through the path of the P2P communication.

Abstract: An information processing device 1 includes a transmission judging section 11 for judging whether to transmit a repetition packet, a life judging section 12 for judging whether to set a life not reaching a server device 3 to the repetition packet, a life setting section 14 for setting the life of the repetition packet to the life not reaching the server device 3 when the life judging section 12 judges to set the life not reaching the server device 3, and setting the life of the repetition packet to the life reaching the server device 3 when the life judging section 12 judges to set the life reaching the server device, and a transmitting section 15 for transmitting a repetition packet having the life set by the life setting section 14, when the transmission judging section 11 judges to transmit the repetition packet.
