1. A method for redundant communication at a network gateway, comprising:
exchanging data packets with a network application via a first access communication interface;
exchanging data packets with customer premises equipment (CPE) via a local communication interface;
exchanging at least some data packets with the network application via a second access communication interface that is different from the first access communication interface; and
representing the network gateway to the network application using a first Internet Protocol (IP) address irrespective of whether using the first access communication interface to exchange data packets with the network application or the second access communication interface to exchange data packets with the network application.
