I'm guessing this is the option in the VNC server properties Connections 
tab under 'Access Control' that has a checkbox for "Only accept 
connections from the local machine."

About which the RealVNC documentation says:

"Only accept connections from the local machine

LocalHost=true|false

The LocalHost option tells VNC Server to only accept incoming connections 
from Viewers running on the local host computer. This is only normally 
used when connections are to tunnelled through a custom transport (e.g. 
serial line, custom wireless, etc) and will therefore appear to the TCP 
stack to originate from the local host. If VNC Server is configured to 
accept connections only via local loopback then the Hosts option is 
ignored."

If that's the trick, then I'll give it a go the next time I'm in to my 
Dad's computer.

I've been reluctant to try it because I'd get locked out of the basic VNC 
service if it doesn't work right off the bat.

I do, however still have an account with a web based remote access 
service, so if I screw something up, I can still get back.

Again, if anyone else sees a glaring mistake in the setup I posted, 
please chime in.

Thanks.
