I was just guessing something. I have obviously no experience with cable
modems as I started with ADSL as soon as it was available and reports
from other people with cable telling me that their download rate drops
dramatically at around 5pm when all the people get home to chat, mail
and browse makes me believe that was a good decision.

Not sure if you can configure the user side of a cable modem in the same
way than the network side. My little wireless gateway with DSL port has
however some configuration lists to block ports in IP specific ways.
It's not as powerful as iptables or those and I doubt the device would
be happy with a long list of rules, but it could be done.

Another interesting option. Our ADSL providers seem mostly to assign
fixed IP addresses, but cable apparantly uses dynamic here too.
