Access to on a local network from internet

[Bob Gargan]

Also with your setup, since all your PCs were using port 5900 then when
inside the firewall, you will refer to the machines by their local IP
(or name) and use port 5900. This isn't the same way you would have to
access them from "outside".

As an alternative, depending on your situation, you could install the
server on a machine known to have clean access to the internet.  Then
connect to that machine.  Once that works, then use that connection to
connect back through the firewall to your internal machines.  Yes this
isn't really required, but it will allow you to simulate the
connectivity.
