RE: cable modem access

["Frank W. Keeney" <FKeeney () hsa com>]

Up until January I had a cable "modem" in my house until I installed
SDSL.

I use a Linux box to act as a firewall for my Win9x/NT computers. I use
ipfwadm which is included with Linux. A sample ipfwadm "firewall"
script:

        I know this group is dedicated to helping network administrators
with firewall issues that they deal with at their workplace, however, I
have a slightly different twist on my problem.  It is not directly
workplace related.  

        I have a cable modem at home.  I have some concerns about the
security of the setup.  I have this installed on a stand alone machine
whose only function is internet access.  I want to change that and put
three other machines on the cable modem through a network.  I have
installed Cat 5 cable, and purchased a 10/100 hub for this activity.   

        I have considered a linux server as a front end and firewall,
however, it will be a learning experience to get it up an running. Is it
the best option as a firewall?  Are there better options?  I have a
win95, a win98, and a NT4.0 workstation that I want to put behind a
firewall.

        My question is how can I protect those machines.  I have another
machine that I can use as a firewall box. I just don't know what is
available for my type of arrangement.
