Abstract
A method, implemented in a router in a Communication Service Provider (CSP) network, includes connecting to a device via at least two connections where a first connection includes a first Wide Area Network (WAN) interface and a second connection includes a second WAN interface; receiving an encapsulated packet from one of the at least two connections where the encapsulated packet is destined for an Internet Protocol version 4 (IPv4) address on the Internet; and creating an IPv4 packet from the encapsulated packet by de-encapsulating the encapsulated packet and including an IPv4 public address in an IPv4 packet, wherein the IPv4 public address is associated with the router.
