Port Scan (3): Some malicious intruder will try to use a 'port
scanner' to know how many ports of your Internet
IP address are open, and they can collect a lot of
valuable information by doing so. Check this box
and the router will block all traffic which is trying to
scan your Internet IP address.

unusable. Check this box and the router will filter
this kind of traffic out.
