Connect RobotStudioOnline Yumi with Virtual Controller


For a test I'm trying to connect a tablet with RobotStudioOnline Yumi with a Virtual Controller runnning on robotstudio 6.04 on my laptop.  
I put the file vc_network_definition.xml in the home folder of the virtual robot with the address of the laptop.
The tablet can ping the address of the laptop but  RobotStudioOnline Yumi can't find the robot controller on the network.
Any Idea to help? Am I trying to do something Impossible?

Thank you
