Does anyone use the KNX APP configuration with Eibnetmux as a knx router? The app finds the interface, but does not receive and does not send knx datagrams. If I turn off Eibnetmux and use the physical interface, ABB works instead.  
(the rest of my configuration works correctly with Eibnetmux: Openremote, OpenHab2).
