I'm using Ubuntu 12.10 and as I know there is already a firewall on any ubuntu system. It's
ufw and because I like fancy gui stuff I can use
gufw, that's very nice.
Now I would like to configure this firewall. I want always a notification if there is some incoming or outgoing traffic. The user should be able to choose
allow always for this or
refuse. Can I do this with
gufw? Or do I need another firewall? What do I have for options? Thank you
