Mediaone's external SB1200 modem does /not/ filter broadcast traffic.
I've seen broadcasts from *.255 before, as well as packets clearly
destined for Mars instead of me. Infact, I would go as far as to
say that it's unlikely any cable modem would filter bcast -> that
is usually reserved for the ISP's routers.
Best advice I can offer you - use a firewall. Cablemodem and xDSL
users alike - these people have great access, but they're clueless
about systems security. I've seen probes from the "10 net" (10.x.x.x)
before, as well as packets with IP addresses clearly forged (somehow
I don't think www.whitehouse.gov would run nmap against me..).
