installed gufw and now im trying to set it up
although i have a router ,im often outside connecting to all lot of public wifi hotspots...
as a first try i set incoming/outgoing to deny and then tried to add some exceptions but nothing moves.
the moment i set outgoing to deny no matter the exceptions no internet traffic is allowed to move.
i also noticed something else ( probably a bug ) :when i set the gufw to incoming/outgoing to deny while im listening to radio on rhythmbox ,the connection/streaming stays open until im forced to close it by hand.
i have the impression that gufw is "buggy".
some help to configure it would be very wellcome..... ?

i would use firstarter but a lot of people in the other forums say its development stopped a long time ago...what do you think? maybe you could recommend me another one or the same....?
