djpic,
For IP Cop you just download and make a CD and then run it on the dedicated machine - I AM NOT a LINUX GURU - it is all gui on the web interface so no UNIX or LINUX skills needed.
I added one of the unsupported add ons - Cop Filter and had to do a little UNIX to install that but they had GREAT directions at the site. Once again this is one of the extra add ons that are not really needed for the firewall and IDS of IP Cop.
As for nics I use 3com, Linksys and it detected the on board nic on the Dell machine I am using.
Makes a nice firewall and IDS that will allow you to do lots of stuff that you would expect on a PIX costing $$$$$$
Go to the website and read through the docs and I think you will see how easy and well documented it is.
I have been using it for several years now!
Just my thoughts!
