Networking / Multiplayer Issue

Hello, We are working at implementing Minecraft Education Edition (MEE) within our school district. We have our users fully licensed thru our tenancy and the latest application version deployed to our Windows 10 v1703 systems. We have an enterprise level firewall in place and Windows Firewall turned on for all systems. Minecraft, Classroom Mode, and Code Connection are configured to be allowed thru the Windows Firewall. All systems have access to the internet.

We are having some issues with multiplayer traffic / connection of users to shared worlds. We cannot determine/pinpoint the traffic that needs to be allowed to go between our security zones in our firewall. We have an admin network zone and an academic network zone. We can see the host and clients connecting out for login to the service.

Here are the scenarios we are testing under (* asterisk for those not working):
- If both MEE host and MEE clients are in the admin network zone, the clients CAN see and connect to the hosted world.
- If both MEE host and MEE clients are on a home network, the clients CAN see and connect to the hosted world.
- * If both MEE host and MEE clients are in the academic network zone, the clients CANNOT see and connect to the hosted world.
- * If the MEE host is in the academic or admin zones and the MEE clients are in the opposite zone, the clients CANNOT see and connect to the hosted world.
- * If the MEE host is in the academic or admin zones and the MEE clients are external (Home), the clients CANNOT see and connect to the hosted world. (Same if reversed)
