Hi! I have a question about issue after iphone iOS 5 update and Fortigate Firewall. iCloud me mail doesn' t connect to server. I receive this error message into iPhone mailbox: Cannot Get Mail The connection to the server failed. Account works fine outside LAN and using Mobile Internet. Can you help me?

How much do you restrict the ports your devices are allowed to access? Port 80 and 443 are not enough for MobileMe/iCloud to work. Apple has good documentation on what ports all their various services need here: http://support.apple.com/kb/TS1629. I have worked through that document and set-up custom services for each that I want to allow so that I can easily add them to service groups to assign to firewall policies. Here' s a screen cap of some of the services I have defined. I haven' t updated it in a year and the Apple document has been updated just a few months ago, so my example is not necessarily all that is required for the new iCloud. A couple that I' m sure it needs are SMTPT and XMPP.

In my config all outbound traffic is allowed for all ports (LAN to WAN)... I don' t understand...

I' m seeing the same thing. If all UTM features are turned off in the policy, it works. I' m not sure which UTM feature is causing the problem.

Anyone find a solution to this? I also have all outbound traffic allowed except for SMTP (excluding our mail server). UTM is enabled for application control and very low level antivirus, screenshot attached for application control. Running V4 MR3 Patch 5
