Configure devices to work with APNs
Mobile device management (MDM) solutions use the Apple Push Notification service (APNs) to maintain persistent communication with Apple devices across both public and private networks. Using APNs, Apple devices learn about updates, MDM policies and incoming messages. MDM solutions require multiple certificates, including an APNs certificate to talk to devices, an SSL certificate to communicate securely, and a certificate to sign configuration profiles.
![A diagram showing how APNs is used with an MDM solution.](https://help.apple.com/assets/664256E0F9FFA26F690A0B01/664256E3F9FFA26F690A0B07/en_GB/541147f50fe816caa340b9f8417c1dc8.png)
For your Apple devices to work with APNs, allow network traffic from the devices to the Apple network (17.0.0.0/8) directly or by using a network proxy. Apple devices must be able to connect to specific ports on specific hosts:
TCP port 443 during device activation, and afterwards for fallback if devices can’t reach APNs on port 5223
TCP port 5223 to communicate with APNs
TCP port 443 or 2197 to send notifications from MDM to APNs
You may also need to configure your web proxy or firewall ports to allow all network traffic from Apple devices to the Apple network. In iOS 13.4, iPadOS 13.4, macOS 10.15.4 and tvOS 13.4, or later, APNs can use a web proxy when it’s specified in a proxy auto-config (PAC) file.
Multiple layers of security are applied to APNs at the endpoints and the servers. Attempts to inspect the traffic or reroute it result in the client, APNs and the push provider servers marking the network conversation as compromised and invalid. No confidential or proprietary information is transmitted through APNs.
Tip: When you create APNs certificates for use with MDM, note the Managed Apple ID (recommended) or Apple ID you use — you’ll need it when it’s time to renew the certificates, which you must do annually. Also, be prepared to update all certificates used by your MDM solution well before they expire. For more information, see the Apple Push Certificates Portal.
