One of greatest and best firewall in Linux is the IPtables firewall but it is command line and for beginners who are conscious about online security, Iptables configuration is a very big headache atleast for me though....
after some searching I found the Firestarter firewall it is simple yet has an advanced GUI for IPtables firewall. Install from the Firestarter firewall from the repository. After installing it will be in Administration ----> Firestarter
Run firestarter and run the wizard select the dial-out device and select
IP address is assigned via DHCP(If it is so ) and go forward disable the internet connection sharing option and go forward and in the next dialog box select
start the firewall now and you are done.It wil run in the background after you install it;Goto Edit-----> preferences to suit it to your needs.To check whether it is running or not go to terminal become root and run
/etc/init.d/firestarter status
it will give the following output
Firestarter is running... ... (warning).
and that's it your own personal firewall is now operational.
