These steps are automatically verified and performed by SIMRIG Control Center. Start the game and follow the prompts issued by SIMRIG Control Center. Or use the auto-configure tool on the Settings Page.
Open a CMD window as Administrator and run the command

This will allow Forza to send UDP packets to your local computer. This is not allowed by default since Forza is packaged as a UWP app.
