Let me put it this way, I have personally found an anon-ftp server with 
company confidential documents on it, that was reachable from the outside 
without the owners knowledge, because there was a port-forward in the 
residential gateway that the owner wasn't actively aware of, and the NAS 
had anon-ftp turned on without the owners active knowledge.

So google had indexed all files on this NAS. I contacted the person (did 
some digging using pictures etc on this NAS) via their employer, and 
talked to the person who had no idea.

Now, with unfiltered IPv6 it would be harder to actually find this NAS, 
but once found, there is no need for port forward for it to be reachable 
from the Internet.

So yes, I can understand the fear and I agree that it's realistic. That's 
why most ISPs have chosen to have stateful filtering toward the customers 
by default.
