Abstract:
A method for establishing remote access of a mobile node to a private network comprising:creating a plurality of successive tunnel segments between said mobile node and said private network, each successive tunnel segment having a source endpoint and a destination endpoint; creating a plurality of successively chained registration requests from each of the successive tunnel segments, wherein said plurality of successively chained registration requests are validated; processing said successively chained registration requests in succession until a secure data transfer pathway is created between said mobile node and said private network, wherein a compound tunnel is composed from the plurality of successive tunnel segments; pre-pending an information packet having a header for one or more successive tunnel segments with an additional header after said plurality of successively chained registration requests are validated, each additional header including an address for a source endpoint and an address for a destination endpoint for the next successive tunnel segment, wherein the last successive tunnel segment of said plurality of successive tunnel segments has its additional header stripped and has an information packet forwarded to its destination endpoint.
