They can't block highly unconstrained, largely unanswerable questions
from reaching comp.security.firewalls, for one.

This is a serious answer, because I'm going under the assumption that
you are probably a business owner or manager whose pinkies happen to
have been broken in a freak typing accident.
You can have a firewall can block everything... but then nothing will
get though. At that point you might as well not have a network
connection.
You want things to get through though, well, certain things. So you try
to choose what to let through. The problem is that it takes a great deal
more information to separate what you want from what you don't want than
can be conveniently communicated in a newsgroup thread. You have people
reading this list who are usually quite generous with the bandwidth
that comes out their fingertips, but this question is broad enough
to be an abuse of that generosity.
What you need to do is either pay someone for their education and
experience in this area or acquire relevant education and experience of
your own, which you may legitimately be trying to do. The open-ended
nature of your inquiry, however, suggests that you have no basis for
estimating what the education will cost... let alone the experience. In
either event, the place to start is your local library. Go to the far
left hand side of non-fiction where the Dewey decimal numbers begin
with zero. Look for books on security and firewalls among those on
Dreamweaver and Excel. They'll usually be about three inches thick.
You'll need to read at least 3 books of that nature before your
bullshit detector can be calibrated to learn anything. At that point,
you might be ready to ask a question or make an intelligent hiring
decision on a security consultant.

If you were Registered and logged in, you could reply and use other advanced thread options
in general; Hardware and Software FW. If you have a cable or dsl connection
with a modern modem, you probably all ready have a HW FW that utilizes
Network Address Translation adequately without a router. You will have to
research that yourself by manufacture or consult your ISP help online. The
Software FW blocks all ports(software) from inbound attacks and unsolicited
port scans. The windows xp/vista FW will only block inbound. Many Software
FW like ZoneAlarm (the easiest free FW available to learn with) also blocks
outbound with permissions that you can assign, but in the case of ZA, a
server will also assign permissions at initial start up of an application
that wants access to the Internet. There are many free FW for trial out
there and a good website would be www.freefirewall.org . I hope this helps
you on your way.
