Rubbish.... That's a home user..... Close all ports because you provide no service.....

Now start talking real world..... Start thinking about _required_ open ports and then continue the discussion......
I'm not discussing anything apperently, with required open ports, same story you can just "download" a different firewall script

also that's not all me post said, I was refering to the defender kind of scriptkiddies... they exist as well as the attacking kind and they don't belong in the discussion on the high up there corporate stuff with required open ports and blah
