What GUI firewall manager should I use to replace Firestarter?

Solution 1:

First of all, the main reason behind Firestarter not being maintained any more is that Ubuntu comes in with the firewall called ufw by default. You can install a graphical interface to ufw by selecting it from the Ubuntu Software Center (package gufw) or by typing

sudo apt-get install gufw

Please note that any and every "firewall" in Ubuntu will be some kind of interface to the iptables. Some of these interfaces are graphical (like Firestarter), some not (like ufw), some are not graphical, but come with their own graphical interface. You will find more information on this page.

Also, please consider the following. Firewall can be of real use if you do understand iptables and the way TCP/IP works. If you do, then configuring the firewall using either naked iptables or some kind of text interface based on config files (like ufw) usually presents no problem.
