PURPOSE: Address saving-type internet connection method using a network address translation(NAT) saves a IP address, embodies a private network with a single IP address, and easily configures various networks. A virtual private network(VPN) configuration method configures a virtual private network, reduces a cost for the virtual private network(VPN) by using IP address saving-type internet connection method, solves a speed problem without a coding and a preservation protocol, and utilizes all conventional public networks. CONSTITUTION: When constructing a plurality of servers such as Web, mail, FTP, and tel-net in order to construct a private network, an internet connection system(address translation function router; 10) constructs a virtual private network about a plurality of personal computers and servers to be connected to a hub is constructed with a single IP address, therefore, the number of IP addresses is reduced in constructing a network or a server. When embodying the virtual private network (VPN), a conventional public network can be maximally utilized without regard to any service company, a construction cost of the VPN and a maintenance cost of the VPN can be reduced. A load of a network device is reduced without using a preservation protocol and a coding algorithm, and a preservation maintenance of the VPN is possible.
