Typically, MDM Servers must reside in the DMZ thereby allowing mobile devices to make inbound connections even when they are outside the firewall. Like other external-facing servers, the ZENworks MDM Server faces the Internet from within the DMZ. This lets the enterprise firewall protect the MDM Server from external attacks.
To enable both internal and external access to the MDM server, certain firewall ports must be open. The ZENworks MDM Server accepts most inbound connections using HTTPS on port 443.
Apple Push Notification service: Both the MDM server and the iOS clients communicate with each other using the Apple Push Notification service (APNs). For outbound connections, the MDM server uses ports 2195 and 2196 to Apple’s 17.0.0.0/8 block. Port 5223 must be open in the firewall to enable mobile devices to connect to the APNs server, so that the APNs can send messages to these mobile devices that are within your network.
Firebase Cloud Messaging: Both the MDM server and the Android clients communicate with each other using the Firebase Cloud Messaging (FCM) service. For outbound connections, open port 443 to connect to the FCM service from the MDM Server as well as the Android clients. For mobile devices that are within your network, to receive messages, FCM typically uses port 5228, but it sometimes uses 5229 and 5230.
A detailed list of the ports to be to enabled for each ZENworks feature is provided in the next section.
The MDM Server and the end-user devices must be able to reach certain endpoints to access apps and services. The endpoint URLs are listed below:
