I just got cable net access, whoopie ;D and now need to install a firewall on it. Before I was using dialup, I didn't worry much about it but now I need help/links on setting one up. A good easy one to setup would be nice.

I'm using Slackware 9.0 and Debian Sid, but want to get Slackware setup first. I used Netconfig to setup the cable modem and get online.

Then I went to Shields Up (http://grc.com) website to see what ports are open and the only one's showing open are ftp, finger and ident, everything else looks okay.

Any ideas/suggesions.
