Necessary Firewall Permissions for SimpleMDM Usage

← Knowledge Base
Question: Many of my enrolled devices will be behind a firewall. What do I need to whitelist on my firewall so that my devices can communicate with SimpleMDM?

Answer: As long as your devices are allowed to contact the public internet over TCP/443, you do not need to make any changes for the SimpleMDM service. Our service IP addresses are subject to change without notice. As a result, we do not recommend whitelisting our service based on host IP addresses.

Additionally, you need to allow communication with the Apple Push Notification Service. Apple has produced a knowledge base article with specific host and/or port information at the following URL:
