Apple Push Notification service (APNs) is a simple, efficient and high capacity transport service that is at the core of the push notifications feature. The service helps in transmitting messages or push notifications to iOS and OS X devices. These devices receive notifications over a persistent connection by establishing encrypted and accredited IP connections with the APN service.

Why isn’t it working for me?
If the APNs isn’t working, there could be a server or client based issue. A common problem is the device being unable to connect to Apple’s server because the device doesn’t have a cellular data account or signal despite being connected to Wi-Fi. As a direct and persistent connection is a must for APNs, the device won’t be able to use the service if the Wi-Fi network has a proxy server.

What should I do?
The address block 17.0.0.0/8 range needs to be allowed in your firewall settings as it is assigned to Apple. Moreover, the below ports need to be opened so that APNs traffic can get past your firewall:
TCP port 2195; which is used to send notifications to the APNs
TCP port 2196; which is used by the APNs feedback service
TCP port 5223; which is used by iOS and OS X devices to communicate with APNs servers
TCP Port 443; which is used when a device is unable to communicate to the APNs on port 5223 as a fall back on Wi-Fi
