Setting up TigerVNC:
- Download and install TigerVNC v1.1.0 from Sourceforge:
Please note that newer versions may have stability issues (I tried v1.2.0, and it crashes all the time), so you've been warned.
- Then, when the TigerVNC icon shows up in the task-bar (it is an eye of a tiger), right-click on it, select "Options", and configure it as shown in the screen-shot below. Note I've clicked on "Configure" to set a password.
- Important! Since you're reading this, you must be conscious about security. Set an exactly 8-character password using no dictionary words and preferably containing numbers and punctuation and other symbols for enhanced security. Write down this password as you will need it in the last step.

Finally, configuring bVNC:
- Create a New Connection in bVNC.
- Under "Connection Type", select "Secure VNC over VeNCrypt".
- Enter the IP address of the computer where you installed TigerVNC in the "VNC Server" field.
- Don't enter a "VNC Username"
- Enter the password you set in the previous step into the "VNC Password" field.
- Tap connect and you should be happily connected over an encrypted channel.
Additional notes for connecting over the Internet:
- If you need to connect to your computer over the Internet and you have a router, you need to forward a port on the router to your internal computer running TigerVNC. Do a Google search for how to forward a port on your particular router model.
- If you are connecting over the Internet, consider forwarding a non-standard external port to port 5900 of the machine running TigerVNC. This way, it will be less likely hackers will attack your TigerVNC service to try to crack your password. For example, forward a random-looking 5-digit port number like 62563 to port 5900 of the computer running TigerVNC.
- You also need to discover your external IP address (you can do a Google search for "what is my ip".
- If your external IP address changes (it is dynamic), it is also advisable to set up "Dynamic DNS" which will track your external IP address so you don't have to rediscover it when it changes.
