How do I configure my UBR 7200 to deny my cable customers from using "linksys" type DSL/Cable routers on my network, and prevent the theft of service that these can enable. Is there a hot sheet of MAC addresses (mfg. code & model code) for these devices? If so how would I obtain it? Also is there a way to detect and deny these devices on another level (as the new linksys routers can "clone" a Mac Address.)
