So it's nonsense, stupid, unpolite (sic) and brain-dead to default drop
incoming traffic? OK, if you say so. I must make a note to inform the
authors of every firewall manual and book i've ever read that they're
How exactly does it "hamper net traffic" to let you time out when
connecting to a closed port?

Yeah, top statement there. Your attacker knows no such thing, all he knows
is he timed out instead of getting rejected instantly. If you try a random
port on some random IP address and you don't get a host unreachable, do
you KNOW that it's up? Of course you don't, unless you control every
router in the world.
You should tone down the insults. Trying to show how clever you are by
being rude is not productive.
Better go now and try to unbind broken services from my external
interfaces like the braindead root that i am. And play with my filter.
Thanks for the laughs.
