<P>PROBLEM TO BE SOLVED: To provide a static NAT formation device, a reverse proxy server, and a virtual connection control device for use in a new network, eliminating the conventional VPN problem and achieving flexible operability and strong security by the addition of quite lightweight software and hardware. <P>SOLUTION: After the static NAT formation device executes authentication to a conductor through a control session, if a terminal issues a connection request to a server in the network existing ahead the reverse proxy server, the static NAT formation device and a stepping node sets a static NAT, and the reverse proxy server sets a reverse proxy, so as to form a data session between the terminal and the server. With such a structure of the network system, it is possible to obtain the connection of the terminal to the server over a firewall, in a virtual connection mode without collision of private addresses. <P>COPYRIGHT: (C)2012,JPO&INPIT |
