Necessary Firewall Permissions for SimpleMDM Usage

Question: Many of my enrolled devices will be behind a firewall. What hosts 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. Otherwise, you must allow communication with the following IP addresses for TCP/443 communication:

52.89.93.58
54.191.186.71
54.68.247.193

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:
