SuperNova Whiteboard Connect and View gives students the opportunity to connect to a teacher’s interactive whiteboard and magnify the teacher’s presentation on their own computer screen.

SuperNova makes use of virtual network computing (VNC) to make the connection between the teacher’s computer and the student’s computer. To learn more about setting up VNC software see Knowledge Base Article - Q122

In this article we will explain the options available to a System Administrator who is attempting to resolve the issue where the teacher’s computer and student’s computer are running on separate networks.


For schools where the teachers and the students do not share the same network, you can do one of the following:

Enable port-forwarding for the VNC port on the teacher’s router. By default the VNC port number is 5900. For help configuring VNC port forwarding on a variety of routers and firewalls please see


If enabling port-forwarding is not an option because of security concerns then it is possible to configure Virtual Private Network (VPN) software, like Hamachi, to securely join both networks together. This allows the teacher to create a secure private network which the students can join.

Once the student has joined the teacher’s secure private network group, the VPN IP address of the teacher’s computer will be available to the student. It is this IP address that the student will need to enter into the SuperNova Connect and View Whiteboard Settings dialog box. To learn more about setting up SuperNova with VNC software see Knowledge Base Article - Q122.

Now, provided the teacher is running the VNC software and the student has correctly entered the IP Address and password then SuperNova Connect and View will successfully connect to and show the teacher’s computer screen.
