How to open up a port on Windows Defender

On the firewall on the server, you will need to create an open inbound port, as we are using port 10401.

When you install Sitebulb Server, the ports in Windows Defender should be automatically opened. However if you find this has not happened, please tell us ASAP!

This guide exists to explain how to do it manually.

Open port via command line

You can do this in command line:

netsh advfirewall firewall add rule name="Sitebulb Inbound Connections" dir=in action=allow protocol=TCP localport=10401

Open port in Windows Defender GUI

Or you can do this in Windows Defender interface, just follow this guide.

Whichever method you do, you want to end up with an inbound rule that looks like this:

Some server hosts may also have a network firewall, and you will also need to open the port up on the network device, and not just on the server.
