This paper proposes a VPN configuration delivery system capable of reducing the configuration burden on users when making remote-access VPN connections and capable of supporting immediate VPN connections to VPN servers created on an ad hoc basis. The proposed system is able to lessen configuration inconvenience and create immediate VPN connections by means of a VPN configuration delivery server that links to the VPN server, generates the necessary VPN connection configuration data, and delivers the configuration data to the client. This paper also reports on the results of verifying the system's operation with an information-card prototype.
