ADDRESS ALLOCATING METHOD IN INTER-PLURAL POINT COMMUNICATION, COMMUNICATING METHOD AMONG PLURAL POINTS AND ITS CONNECTING DEVICE

摘要

PROBLEM TO BE SOLVED: To reduce the setting burden of 2nd point sides by allocating an address which is different from that of a destination terminal connected to a terminal in the 2nd points but common among all of the 2nd points. SOLUTION: 2nd points 200 respectively have an address converting part such as PROXY server and fire wall for converting the private address of a client machine 201 into a global address. In a network connecting plural points, connection destinations of communication data having the same connection destination address are divided by converting the connection destination address into the address of a connection destination terminal for the communication data on a communication path between one point to which the terminal to be a connection destination candidate belongs and a connection source. Thus, it is possible for the 2nd points 200 to easily and directly communicate with a network 1 and to construct a virtual private network(VPN).
