Linda:
Not to sway you from building the firewall yourself but
have you looked at the graphical firewall configurator at:
http://firestarter.sourceforge.net/
It requires gnome either 1.0 or 1.2. May sure you select
the proper one and it allows an easy to configure firewall
via graphical interface that can run in "X" mode or out of
X mode. You can also add your own rules that the firewall
does not produce. I set it up on one of my machines in less
than an hour and after having constructed a rather sloppy
firewall via IPchains on my first attempt which took several
days it took me 1 hour to get and setup this nice graphical
tool. I would really give it some consideration as it would
save you lots of time. It used IPtables or IPchains. The
hard
part of my installation was just getting the low end machine
I set it up on to run X server.
Just a thought...
