ROUTER, PACKET FORWARD METHOD, AND PACKET FORWARD PROGRAM

摘要

PROBLEM TO BE SOLVED: To solve the problem in security and the problem that only one P2P application software program can use one port since each P2P application software program does not specify a partner when the P2P application software programs use their UPnP IGD port mapping functions.;SOLUTION: A port mapping control section 204 accepts reservation of a port mapping including a destination port and a communication protocol in duplicate with the other port mappings. When the port mapping control section 204 is notified that a computer connected to a LAN receives a packet, the port mapping control section 204 adds the port mapping accepted as the reservation to a port mapping table as a regular port mapping.;COPYRIGHT: (C)2007,JPO&INPIT
