When the virtual private network access program in the data unit 112 is executed, the executed virtual private network access program outputs the connection state of the main screen and the USB memory to the monitor (S410), and the authentication server 300 according to the execution of the virtual private network access program. ) And transmits the unique number of the USB memory 100 to the authentication server 300 (S415).

The authentication server 300 determines whether or not the unique number of the USB memory 100 is permitted to be used as a fixed IP address (S420). A fixed IP address corresponding to the unique number of 100 is given to the USB memory 100 and recorded in the data unit 112 in the USB memory (S425). On the other hand, if authentication fails, the authentication failure message is output to the monitor (S430), and the process returns to or ends at S410.

On the other hand, if a fixed IP address is given, the user computer 200 and the virtual private network server 400 is a Point-to-point tunneling protocol (PPTP) connection method or Layer2 tunneling protocol (L2TP) layer 2 tunneling protocol ) It is determined in which of the connection method can be connected (S435, S440). According to Figure 4, the PPTP connection method was determined before the L2TP connection method, the determination order of these connection methods may be reversed.

If any one of the two connection methods is possible, the user computer 200 requests a point-to-point protocol (PPP) tunnel connection to the virtual private network server 400 using the fixed IP address (S450). If the connection is not possible in any of the four connection methods, the virtual private network access program 120 outputs the tunnel connection error message to the monitor (S445), and returns to or exits from step S410.

When the user computer 200 and the virtual private network server 400 are connected by a point-to-point protocol (PPP) tunnel, the user computer 200 generates a virtual device (PPP) having a fixed IP address (S455). Computer 200 changes the default gateway of the user computer to a fixed IP address (S460).
