Methods and systems for managing virtual addresses for virtual networks

The method and system which enable a virtual private network between the 1st and 2nd processors concerned using at least one additional processor separate from the 1st and 2nd processors. In an additional processor, the 1st imagination and the basic address of the 1st processor are judged, and the 2nd imagination and the basic address of the 2nd processor are judged. Moreover, based on all these addresses, a virtual private network is enabled on a basic communications network by an additional processor by transmitting the 1st imagination and a basic address to the 1st processor, and transmitting the 2nd imagination and a basic address to the 2nd processor, respectively.
