1. A method implemented by a network element, the method comprising:

  • receiving a data packet transported on a backhaul link at the network element;

    de-capsulating the data packet, if the data packet is an upstream data packet;

    performing an identification of whether the data packet matches an internet protocol (IP) access control list (ACL) or a tunnel endpoint identifier;

    performing a network address translation on the data packet with the network element, in response to the identification identifying that the data packet does not match the IP ACL or the tunnel endpoint identifier;

    offloading the data packet from the backhaul link at the network element in response to the identification identifying that the data packet matches the IP ACL or the tunnel endpoint identifier; and

    communicating the data packet from the network element to a gateway or general packet radio service support node using a generic routing encapsulation tunnel in response to the identification identifying that the data packet does not match the IP ACL or the tunnel endpoint identifier.
