iTeleport Connect will launch an internal VNC server if you don't already have one running. What if I already have a VNC server running?
If you've already set up a VNC server, click the Advanced Settings option, and choose the option to Search for a VNC server, and give it the port your VNC server is running on (the default VNC port is 5900).
Once iTeleport Connect is Connected, you're done with setting up your PC.
