I have installed and activated the GUFW and have added and additonal firewall rule (FTP, In/Out = Deny all).
I really do not know anything about firewall rules and therefore have no idea if there are any others that can or should be added to the list.
A Google search on "GUFW Firewall Rules" provided me with this information : http://www.linux.com/learn/tutorials/429427:create-firewall-configurations-easily-with-gufw-on-ubuntu
Unfortunatelty I do not understand anything about Amule, Deluge, Nicotine etc etc and nothing about FTP. HTTP, IMAP etc etc that the article refers to so cannot make an informed decision as to what to allow, what to disable and what additonal rules should be applied (if any).
I don't expect anyone to take the time to try to explain everything I need to know about firewalls, rules and the types of traffic , however, if anyone has a good article to point me to that would help me undersatnd this a little better so that I can create firewall rules that will strengthen my pc's overall security, that would be very helpful.
