Abstract

A method of identifying an egress point to a network location includes receiving a client connection from an external network (e.g., the internet) and retrieving an egress point identifier from an egress data source (e.g., a database, look-up table, hash table, data object etc.) for the received client connection. The egress data source stores egress point identifiers associated with at least one of an internet protocol address and a subnetwork. The method further includes binding the client connection to an egress point corresponding to the retrieved egress point identifier, encapsulating packets of data received from the client connection, and sending the encapsulated data packets through an instantiated network tunnel to the bound egress point. The method includes decapsulating the encapsulated data packets at least near the bound egress point. A default routing policy may then guide the data packets to the egress point.
