GUI for iptables?
I would like to secure my server and it seems that IPtables is one of the first steps. Unfortunately editing the rules in a terminal is a bit complicated and dangerous (those who ever did an iptables -F will know what I mean ;) ). Could you recommend any good graphical interfaces for managing my IPtables rules?
Firestarter has always worked well in my opinion. It supports a robust GUI and supports all options of iptables.
sudo apt-get install firestarter
Try Firewall Builder.
sudo apt-get install fwbuilder
