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.



Yes, not to say there aren't always exceptions, but I'm still willing to
bet firewalls, for many people, have caused more problems than they have
solved.

Our ISP has a master firewall on his fiber connections that is WAY more
powerful than anything I would pay for. We are three layers inside his
network. Each access point has it's own powerful firewall. This feeds
through the modem to a router with a firewall. That's five firewalls
between me and the fiber. If they want in bad enough to get through all
that they can have it. I can't see where having a firewall on my
computer is going to make any difference.

Besides all that, if they want you bad enough they WILL get you.
Firewalls are like padlocks. They keep honest people honest. The only
sure fire way to keep someone out of your computer is to unplug the
network cable, remove the modem, and unplug it from the wall. Anything
short of that.......NO guarantees.
