How to Find a VNC Server Port

VNC can be a handy way to provide remote desktop access to your computer whether at home or at work. Since the computer running VNC Server software is usually protected by a firewall, knowing which port is in use by the VNC Server software is a necessity when configuring the firewall to forward VNC connection requests to the VNC computer.

Things You'll Need

• Microsoft Windows Computer

Instructions

1. Click “Start,” then click “Programs” or “All Programs,” and then click on the VNC program group located in the program list that appears.

2. Click on the “VNC Server” selection displayed in the drop-down menu that appears and the VNC Server configuration window will display.

3. Locate the “Incoming Connections” section in the upper-left corner of the VNC Server configuration page.

4. Note the port numbers entered in the “Main” box and the “HTTP” box. These are the ports used by the VNC Server software to receive connection requests.

Tips & Warnings
