Firewall & Ports 03

The first question parents ask schools that are implementing mobile devices is in regards to security. And they have every right: we need to protect student privacy and data - even more so when we think about the mobility iPads introduce to Education.

Based on this, the first reaction schools have is to block everything using proxies and firewalls. This is certainly the most common decision when using computers, but it has the potential to drastically impact the use of mobile devices - especially iPads.

When school iPads and MDM servers are separated behind a firewall, they are unable to effectively communicate. If your school is suffering from many pending commands generated by your MDM provider, it’s possible that some of the required TCP ports are blocked by your school’s firewall.

Therefore, it’s crucial to make sure network configurations are properly setup to allow communication between your mobile devices and the MDM server. Through this configuration, student data stays safe, and schools can get the most out of mobile learning.



A port is a location used for passing data in and out of your device. If your school uses Wi-Fi behind a firewall, or a private Access Point Name for cellular data, you'll need a direct, unproxied connection to the APNs servers.
