Hololight Space network port requirements

Hololight Space uses a number of network ports to communicate data between the server and client. If these ports are closed, the features dependent on them won’t work. Below are the network ports that you need to open to fully use Hololight Space.

The table lists the default ports Hololight Space uses,but yYou can also define many of the ports these protocols use yourself. To do this, connect to Hololight Space with a client device, use the Quick hand menu, and go to Options > Meeting settings to change which ports Hololight Space uses.

NOTE
If the network in which you are using Hololight Space doesn’t require use of Windows Defender Firewall, you can disable the firewall and use Hololight Space without opening specific ports. See Turn Microsoft Defender Firewall on or off for more information on how to enable and disable Microsoft Defender Firewall.

Each additional instance of Hololight Space will then use the next port. For example, the second instance of Hololight Space will use port “10000”. The third will use port “10001”.
