Subject:   using IPFW as a firewall

I've started playing around with IPFW in order to boost up the protection
around my home network.  I've seen some recommendations as to what to
filter out, but I haven't seen many explicit examples of what rules will
make up a nice simple firewall.

My home net consists of the freebd box and two NT boxes.  The freebsd box
is acting as a firewall.  My goal is allow my NT boxes unhindered access
to the home net and to the Internet but prevent everything else from
coming in.  What I don't know is what to block.  And how to do it.  I've
been through the examples found on the freebsd website and through stuff
I've found with search engines.  Mostly, I wind up blocking something I
shouldn't and things stop working.  I've started looking at /etc/services
for an indication of what's necessary for my goals.  I'd like some
guidance.
