ABSTRACT:
A network device has a network interface to allow the device to send and receive traffic across a network. The device also has a cable connection to allow the device to exchange data with at least one other device across a cable network. The device has a processor to receive traffic having a network identifier through the network interface and determine if the network identifier is associated with a virtual private network. If the network identifier is associated with a virtual private network, the device then routes the traffic to an appropriate receiving entity through the cable connection if the network identifier is associated with a local are network.
