When you have your Firewall enabled and try to use Mythware Classroom Management Software connection or functionality could be compromised if the ports are not the ones we use.
Below are the ports we use:
4604, 4605, 4806, 4809, 5512~21714
Mythware also uses between 5,000 and 10,000 randomly generated ports when the teacher program starts. During installation, Mythware automatically adds firewall exception rules for its .exe file.
