VNC FAQ-o-Matic : VNC and Firewalls : How can I tell if my firewall is setup correctly?

It can be frustrating to debug a firewall setup while you’re *behind* that firewall. With some firewall/routers, even if you have the firewall’s port-forwarding for VNC setup correctly, you may not be able to connect a Viewer to your Server, using the “real world” external IP address that you just (tried to) enable. This will result in the cryptic but popular “error 10061” if you try it. Fortunately, there’s an easy solution. Just open a web-browser on your PC that’s the VNC Server you want to test, and point it to http://www.GoToMyVNC.com, and run that scan. If this scan can detect your VNC Server, then your firewall is setup correctly.
