KNX IP Devices not being found when using Parallels on a Mac?

Sometimes when using Parallels on a Mac it's not possible to connect to a KNX IP Router or IP Interface. This is due to the type of connection between Parallels and the Mac Network connection.

To solve this right click on the Windows desktop icon on the Mac menu and select configure. 

Then change the network connection to Bridged Network: Default Adaptor. 

ETS should now be able to see the devices again as the interface will have reset. It will take a few seconds for ETS to scan the network connection again.
