SmartClass Apps will need unrestricted access to these URLs and IPs (Whitelisted) 


  • www.SmartClassPlus.com
  • www.roboteltest.com
  • www.robotelapps.com
  • SmartClass Content download:
  • speech.googleapis.com
  • api.ispeech.org
  • License Manager:
  • SCX:

TCP listening ports that are needed for installed SmartClass apps.

These TCP ports should be available (opened) for SmartClass apps:

  • Teacher Station TO/FROM all Students Apps:
    80, 33370, 33378, 33379, 33389
  • BYOD Manager TO/FROM all Students Apps: 
    33359, 33389, 80
  • BYOD Manager TO/FROM Teacher Station:
  • Homework Manager FROM Internet:
If port 80 is already used for Web manager, it can be customized in the Web Manager configurations. 
If port 80 is used on the public IP, a different port can be used to redirect traffic to the local IP for the Web manager.  Ex. 8080


URLs and Pubilc IPs addresses

In some cases, is good to look at the  Resource Monitor

(Task Manager > Performance Tab > Resource Monitor in the Listening Ports Tab)

It will show the ports that are being used, and possibly free-up the port needed for SmartClass.
