Here’s a cool DIY I stumbled onto today that shows you how to setup a custom firewall using iptables. This might not be for those of you who already have a GUI server management system but it’s good to know just in case your GUI goes down…
After getting some problems with firestarter i decided to get knowledge about iptables and how to set my own firewall script and want to share this experience for users who want to set a custom firewall up quickly.
The purpose of this guide is to provide a basic knowledge about iptables and then help to create a firewall script.
The final step will be to make the script running on each boot.
