Verifying the UPnP support

How to verify UPnP support for Vision 365

Starting with version 10.6.1420, the Vision 365 Teacher application added support to connect through the router by using the Universal Plug and Play (UPnP) protocol.

You use this functionality when direct network connections between the teacher and students' devices are not possible. We hope that this provides the needed support for the teachers that run their classes online and remotely.

For more information about the UPnP protocol, refer to the following link.

There are several prerequisites for this functionality to work:

• Support for the UPnP protocol in the router
• Network Discovery turned ON in the active network profile
• the IP restriction in the Vision Portal is different from the "Match the teacher IP address" option

 How to verify that the prerequisites are met:

There are many types of routers and they must be verified according to the manufacturer of the router.

For example:

• https://eu.dlink.com/uk/en/support/faq/routers/wired-routers/di-series/how-do-i-enable-upnp-on-my-router

To verify the forwarded ports, you can use a simple port mapping tool such as UPnP Wizard.
