So here is the result: As you can see there are boxes for al routers and computers, with the power button you can swicth on or off the servers or restart the internet connection. With the setup button you can go to the management web interface for the servers or routers. In the bottom of the picture you see the clients who have got IP address, their status is checked with arping, so even with a switched on firewall you can see the status.
