I'm looking to change my firewall from IPCop to something that runs off the CD. it needs to have support for at least the intel and realtek line of NIC's. also, a web-based admin panel is required.
I know you are looking for a cd-based version, but I've been using Smoothwall firewall a bit in a lab class I'm taking and it seems very competent. It has a web interface and supports all sorts of nifty features. Check it out at: http://www.smoothwall.org/
Sorry, I can't really contribute anything with regard to something that runs directly from cd.
