As the devices to be managed are mobile and are always on the go, you need to expose your MDM server, to the external networks. This ensures the devices can contact the MDM server, ensuring continued management of devices. For those concerned with the security aspect of server exposure, you can use Secure Gateway. As the name suggests, Secure Gateway adds an additional layer of security ensuring all the incoming communications are directed to the Secure Gateway instead of MDM server. The Secure Gateway acting as intermediary, then routes the communication back to the MDM server. Secure Gateway ensures the MDM server is not directly exposed to the Internet, thus securing it from risks and threats. Secure Gateway also ensures the users cannot access the MDM server(web console) through the FQDN/IP of the machine running Secure Gateway. You can know more about configuring Secure Gateway in about 3 minutes through this demo video.
Ensure port #9383 is open and accessible on the machine running the Secure Gateway.
If you are using self-signed certificates,
If you are using third-party certificates,
Follow the on-screen instructions to complete the installation.
To verify the Secure Gateway has been installed and running successfully, go to services.msc and ensure ManageEngine Secure Gateway is running.
1. If there are issues with communication to/from the Secure Gateway, ensure the machine on which Secure Gateway is installed, is running and the network connectivity allows it to contact the MDM server.
2. Check if the Secure Gateway is running on the machine, as explained above.
3. If you are using third-party certificates, ensure the certificates have been correctly copied as explained here.
If you still face the issue, contact MDM Support(firstname.lastname@example.org)
