There isn't an easy way to keep extra protection from these scans, BUT
some routers/firewalls will block all connections from a particular IP
address if it detects that the remote system is trying to do port scan
(I believe some of the Netgears do this, but it has been a while)...

>Both of my networks are behind linksys routers. I have to forward 3389 to a local IP on the Host network or I am unable to connect remotely. If I set ICF to allow the remote access I have an open port. If I dont forward 3389 and disable ICF I am unable to make remote connection. Is there a way to stealth or at least close 3389, or to specify what IPs it will allow a remote connection from?
