    Frankly, you don't. Native push notifications require the use of the GCM servers in the internet. Most customers allow SMP / Afaria to connect to the notification servers GCM, APNS etc and open their WiFi infrastructure in a way to give the devices also access to those servers. You should be able to nail down the ports and traffic using your firewalls etc to prevent stuff from going through that is are not notifications.

    Two workarounds:

    1. Use devices that do not have an internet based notification system (e.g WindowsMobile, WinCE) ;-)
    2. Build a notification system on IP base - e.g. have your app poll your server regularly for new items. Problem: Battery life will go bad on you as the app needs to be active a lot more and consumes much more battery this way. This is the exact reason, why the notification systems exist - the OS can receive notifications much more efficient as any app running in a sandbox could.

    Under the line it is a take-it or leave-it situation. A simple fact of modern mobile life that you can love or hate :-)

    Cheers,

    Dirk
