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 once, 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

Without the use of use of a script similar to this you cannot get notifications like that easily with gufw. However is an alternative that might work called FireHOL. Excertpt from the FireHOL website: FireHOL is secure because it has been designed with the right firewalling concept: deny everything, then allow only what is needed. I'm not sure if there is any type of allow once setting but besides that it looks pretty good. It is a non gui program, but there doesn't seem to be any alternative program that can do what you want.

Server Fault similar topic here.

Well researched answer. Perhaps a list of alternatives to the script and FireHOL from the ServerFault link would be nice... – Scott Goodgame Apr 10 '13 at 19:06
Thanks for the feedback. From the research that, I've done I haven't seen any alternitaves to FireHOL. :( – Gav Apr 11 '13 at 0:14
Thank you for the information. This is good to know, but somehow Im disappointed that there are no other options :( The first script is nice, but it´s just a notification - I dont have the choice to allow, deny the in/outgoing address. And FireHOL is, as I understood, outdated. – silla Apr 12 '13 at 9:03
Its a 5 year old application, has anyone actually tried this? – Meer Borg Apr 13 '13 at 17:36
