How to shut down people on a lan network

[P3eren2708]

Hi, im a teacher in a danish high school. My students play a LAN game, even when were in class, on a LAN network that they create themselves on our schoolnetwork, they dont got internet when they play LAN, but they play games all the time together. How can i shut down their network without them knowing what is happening?

i cant find answers on google, so i hope you can help me in here.

Thank you!

Do you know what game it is? Because you could possibly find out the ports it uses to communicate with the other computers in the game and get your IT admin to block those ports on the internal network. Thats the only way I can think of

Does the school have a Technology Coordinator? If so just notify him/her.
