Communications

Bind to IP

Use this option to restrict access to the service through one specific IP. The "All unassigned" option allows access through all the possible IPs for the computer.

Protocol

Choose between the http and https protocol. The https protocol uses SSL. Hence, it's more secure.

Port

Choose the port number for this computer to be accessed.

Use UPnP

If you support UPnP, check this option to make this computer available from outside your LAN in the port number chosen in the 'Port' field. If this port is already in use in the router, you might see this error message: "UPnP Error: This port is assigned to another service/computer"

If this happens, choose a different port number in order to use UPnP.

Enable Dynamic IP Address Resolution & Shared SSL Certificate

This option works as a Dynamic DNS service to link your IP to a public address in ThinVNC.net and provide you with a Pin code that identifies the ThinVNC server's IP address uniquely. Also in this way you use the SSL certificate provided by the ThinVNC.net site. It is a simple way to provide public access to ThinVNC.
