Beat that horse...
Scenario C is assuming the following points.
1. A single remote user with a software firewall, who doesn't belong to
a larger corporation, a one person organization. You're supporting them
as a contractor.
At your location, setup a SSH server available on the internet with
password logins disabled and keys for various users who need your
support. On their machine a PuTTY configuration (or similar client)
with all the port forwards setup and the connection details configured.
Have the client connect initiate the putty connection (as simple as a
double click) which forwards the port for VNC to the SSH server on a
predestined port. Connect to this port and take over their machine.
Total user work required, double clicking on a PuTTY connection.
A. the user doesn't have putty installed. Someone (meaning me) has to talk them thru it. ("now type -L 5900:localhost:5900, oh wait, not the number one, but the letter L ah heck...")
B. much of the time, the user can't spell "port forwarding", much less do it. Hence in many situations they are connected to internet directly and we just tell them to have windows firewall allow VNC server port access.
C. If the user can get this setup without too much assistance, they can setup their own SSH daemon and let me come in under RDO or VNC or whatever. So the conversation is moot.
