Abstract
A method for creating a secure link between any two endpoints in a network comprises: assigning a unique identifier to each endpoint of a network; for each endpoint in the network, transmitting the unique identifiers associated with each of the remaining endpoints in the network to said endpoint; establishing a secure link between a source endpoint and a destination comprising: transmitting a data-session establishment packet from the source endpoint to the destination endpoint via a symmetric NAT device; wherein the data-session establishment packet comprises the unique identifier associated with the source endpoint; performing a matching operation at the destination endpoint to match the unique identifier associated with the source endpoint with a unique identifier known to the destination endpoint; and upon matching of unique identifiers then creating a forwarding table entry for the destination endpoint based on the source address and source port associated with the source endpoint.
