VPN CONNECTION SYSTEM AND VPN CONNECTION METHOD
First Claim
1. A VPN connection system comprising:
- a client device configured to generate a client authentication data in response to a VPN (Virtual Private Network) connection request;
a relay server device configured to relay a communication through a protocol which is different from an electronic mail; and
a VPN server device configured to establish an always-on connection with the relay server device through the protocol,wherein the client device is configured to establish a connection with the relay server through the protocol to transmit the client authentication data to the relay server,the relay server device is configured to relay the transmitted client authentication data to the VPN server device, andthe VPN server device is configured to perform an authentication of the client device based on the client authentication data, and to report a failure of a VPN connection to the client device when the authentication is failed, and to implement a VPN connection with the client device when the authentication is succeeded.

Abstract
For establishing a VPN connection in the call-back type, a VPN server establishes an always-on connection through a unique protocol different from the electronic mail delivery system. A client generates a client authentication data used for the client authentication implemented by the VPN server, and establishes the relay server through the unique protocol to transmit the client authentication data. The relay server device relays the client authentication data to the VPN server through the unique protocol. The VPN server implements the client authentication based on the relayed data. The VPN server establishes the VPN connection with the client based on the result of the authentication.
