Abstract
There have been provided in the present invention a method for establishing a dynamic tunnel of securely accessing to a private LAN and apparatus therefor. In the method of the present invention, a source tunnel server is disposed on a routing device through which a source host receives/transmits IP data packets, while a destination tunnel server is disposed on a routing device through which a destination host receives/transmits IP data packets. Subsequently, a secure communication tunnel is established automatically rather than manually between the source and destination tunnel servers, without requiring any IP address to be provided for the access servers with respect to corresponding private LANs. Moreover, the communication tunnel can be canceled upon completion of communications.
