Sometimes images speak louder than words, so we've compiled a list of images to show you exactly what you need to do in order to allow the Master Server to work on your Windows Server either in your home or in the cloud!
First you need to open your **Advanced Firewall Settings"

After that, just keep all the checkboxes at default (checked). Click Next
Lastly give it a good name that is easy to find and click Finish
