Re: Security with Cable Modem and ComCast?

Yes, you can change the MAC of a cable modem by surgery. That would let you run an unregistered modem so long as the other modem with that MAC was turned off.

It is physically impossible to see a neighbor's upstream. The cable modem does not have a receiver that can be tuned to those frequencies.

Not only that, the Port to Port isolation @ the Tap would severely degrade the signal before it would enter the neighbour's drop.

I think the poster was more concerned about opening up the network in windows and seeing all his neighbors (and them seeing him). Rather than neighbors "sniffing" his traffic. This has been stopped by the cable modems no longer allowing in and out traffic over those ports that are used.

Broadcast packets can obviously still be captured.
