I am willing to demand my freedom.
When I pay to an ISP for internet, I want to have all ports in/out working.
If I don't want something working, I filter it at *my* firewall.

When code red/nimbda hit some time ago on port 80, nobody suggested blocking 
port 80 for those II$, right? But when a worm hits on less popular port, people 
start attacking the symptoms, not the cause. Am I missing something?
