After installing AlertMobile Gateway, a separate Windows service is created (refer to the screenshot below). As with all Windows background services, this service can be started and stopped.
If you wish to change certain AlertMobile Gateway settings (there is no configuration GUI), you must stop the service and open the "AlertMobile.Gateway.WindowsService.exe.config" file.
The port numbers can be modified in the userSettings section:
Once the file has been modified, restart the AlertMobile Gateway service to apply the changes.
