Try ShieldsUP! from Gbison Research to probe your ports and see if any are open they should all be closed or better yet stealth. Arno's Iptables Firewall is a script for iptables that you should be able to run from the ramdisk as long as you modify the path where it looks for the configuration file and change the default eth0 that is in it for for the gateway to the internet the files are well documented with comments so you should have few problems.
