What ports and url/ip does iMessage use? Corporate firewall and proxy need opening.
Hi All
Hope someone can help. iMessage is causing problems for iPhone users in our schools due to the fact the urls, IPs and ports are all hidden behind the messaging front end of iOS 5. Can anyone tell me which urls/IP addresses/ports I need to get opened through my corporate firewalls and proxy servers in order that iMessage can work for these users?
Thanks
Jon.
