1. A system for providing data filtering from a data network comprising:

  • a data network termination device comprising a packet counter, wherein the packet counter determines a number of packets sent to a subscriber device from the packet counter (herein, “

    downstream packets”

    ) via the data network and a number of packets originating from the subscriber device and sent to the packet counter (herein, “

    upstream packets”

    ) via the data network;

    a data gateway agent, wherein the packet counter is accessible to the data gateway agent; and

    a datastore accessible to the data gateway agent for storing a data transfer rule selected by a subscriber, wherein the selected data transfer rule comprises packet filtering criteria selected by the subscriber, andwherein the data gateway agent comprises instructions that cause the gateway agent to;

    receive a packet prior to receipt of the packet by the packet counter;

    access the data transfer rule stored in the datastore;

    apply the packet filtering criteria to the packet to determine whether the packet violates the data transfer rule;

    send a notice to the subscriber when the packet violates the data transfer rule;

    receive a request to reverse the determination made by the data gateway agent regarding the packet;

    reverse the determination made by the data gateway agent regarding the packet in response to the request;

    modify in response to the request one or more packet filtering criteria of the data transfer rule applied to the packet; and

    apply the data transfer rule as modified to subsequent determinations of the data gateway agent.
