Well…
I can’t argue with -that-. 
But I did as you asked… looked at Windows Firewall.
I notice that Cubase 7, Bonjour and Bonjour Print Services are already on the list. They all have the Private box checked, but the Public box unchecked. I assume that’s normal?
Now: There is also a whole other area where one can selectively enable UDP and TCP ports for each program.
This may not matter but I noticed that the Vienna remote I have has several specific ports enabled.
Where next?
