cable modem access

[twalls - Troy Walls <twalls () acxiom com>]

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.

Any help or suggestions would be appreciated.

Thanks
