KISS My Firewall
KISS My Firewall is a FREE iptables script developed by Steve Eschweiler and is released into the public domain.The home page for this firewall script is http://www.indotek.com/kiss/
It is an easy to use firewall script that many webmasters prefer to install on their web server. However it is not made with OpenVZ virtualization in mind, so if you simply download the KISS script from it's homepage and try to run it - it will not work. We made a modified version of the script that works with OpenVZ VPSes and have put it for download in our download area.
Please note that we DO NOT RECOMMEND that you use this firewall script unless you have read it all and fully understand what it does. For instance by default it will disable outgoing pings and traceroutes from your VPS.
