Push the Settings button to get to the settings screen, which is shown in the following screen shot.
It allows you to configure the following global settings.
FEAT VPN Service. Starts and stops the FEAT VPN service, i.e., the L2TP server that FEAT VPN runs on your Android device. If you temporarily do not need FEAT VPN, turn the service off to save memory. While the service is running, the FEAT VPN logo is shown in the status bar of your Android device.
Start On Boot. If this is enabled, then the FEAT VPN service automatically starts when you turn on or reboot your Android device. If you use FEAT VPN only occasionally, then you may not want to start the service automatically and ,instead, manually start it when needed using the previous setting.
Log Level. When you report a problem we may provide you with a log level string. This is a sequence of 18 letters that, when entered here, enables more detailed information about your problem to be logged in the FEAT VPN log.
Open Native Client. This setting is only available on Android tablets. If this is enabled, then FEAT VPN automatically brings up the built-in L2TP client on launch. So, you start FEAT VPN from the Android launcher, FEAT VPN comes up and instantaneously opens the built-in L2TP client, which then allows you to establish a VPN connection. This essentially saves you one click. Otherwise you would start FEAT VPN and then push the Connect button on the main screen to bring up the built-in L2TP client.
