The "firewall capabilities" used by most of these modems is called NAT
which stands for Network Address Translation ( there are other features
available ). What this basically does is prevent an outside connection
to an inside PC because there is no direct access via an outside IP
address to an internal IP address. When you request an outside
connection, lets say a connection to a web site, the modem automagically
provides a temporary connection for you and drops it when the request
has ended ( the web page has been loaded ).

Yes, exactly. I've never understood the Wild Eyed(tm) insistence on a
firewall, as I imagine there very few installations where a user's computer
is directly on the Internet these days. I always run behind a router,
and thus don't need a firewall. If you have your cable modem plugged
into a switch or router (ie, if your computer is on a 192.168 network),
you don't need a firewall. And yet I can't get Windows to stop complaining
about the fact I don't have the firewall turned on.

My router has it's default route set to my PC, so I get all sewer
overflow from the wasteland, on purpose. I hate it when stupid
things do not work because of over-zealous 3th party gadgets.
For XP btw:
Control Panel::Security Center::Change the way windows alerts me
Uncheck firewall.
