vfighter

@Iwalter Thanks for reply. Everything works now as expected. With IP 255.255.255.255 selected on IPad. The Firewall difference did the trick. Thanks for your great effort! Daniel

@Iwalter I have downloaded the App and tried to get it working (I use an ethernet connection). I get the IPad showing the datas from DCS but inputs from IPad to DCS are not working (button press). Is it really only working with both devices connected to Wifi? I tried allready all the troubleshooting advices. The APP looks awesome! Daniel
