1. A method for performing targeted filtering of network traffic generated by user equipment (UE) devices connected to a customer premise equipment (CPE) device in a communication system that includes a distributed residential gateway, the method comprising:
determining, by the processor in a computing device, whether there is a preconfigured virtual local area network access control list (VACL) on the CPE device that lists source internet protocol (IP) addresses from which the CPE device will filter outbound traffic in response to determining that the UE device is a RFC 3203 compliant device connected to the CPE device in a home network;
generating, by the processor in the computing device, a quarantine request message that includes at least one of an IP address or a media access control (MAC) address of the UE device in response to determining that the preconfigured VACL on the CPE device lists source IP addresses from which the CPE device will filter outbound traffic; and
sending, by the processor in the computing device, the generated quarantine request message to a bridged residential gateway (BRG) associated with the CPE device.
