Minecraft (retail edition) Firewall Exceptions

[DavR]

Does anyone happen to know the firewall exceptions for the retail/Java edition of Minecraft? We have one child that our SEND team want to have access to his personal Minecraft stuff at school as bribe / reward.

 

I've got as far as this article for Smoothwall - https://kb.smoothwall.com/hc/en-us/articles/360002031030-Allowing-Access-to-Minecraft-Using-Smoothwall-Filter-Firewall. We're not using a Smoothwall firewall though, LGfL customer.

 

I've allowed the following addresses through our filtering:

 

• Mojang.com
  
• minecraftprod.rtep.msgamestudios.com
  
• Minecraft.net
  
• xboxlive.com
  

 

I now need to open ports 25565 and 19132, but I need to know what ranges to open them too, our firewall people do not like allow all rules.

 

Any advice from those who have achieved this gratefully received!
