The stratux guys came to the rescue on this one, connecting iFly with stratux via wired Ethernet connection (no wifi.) 1. Be sure the iFly computer is not blocking UDP port 4000 (check firewall.) 2. Open a web page to the RPi running stratux. 3. On that window, click on the "settings" tab. 4. On the right-hand side of the settings page is a block that says "static IP" so in there, insert the IP address of the computer that's running iFly. 5. In a few minutes, if iFly is already set to have a stratux as a connected device, they will finally sync up and you'll get ADS-B data on your Win (the only desktop OS that iFly currently runs on) desktop that's running iFly! Very, very cool.
