Have installed a EdgeMax X router with Statt IP because AirPort Extrem eated bandwith with or new 1Gbit/s connetion.
We run a OSX Server, only CalDav calender for the moment.
CalDave calender works, we hade some problems with it. It worked only outside the firewall but thats solved.
Left is on problem.
Push Notifications don't work. If I manuellt reload anny device, computer outside or inside the firewall a change in the calender occure. If I set calender account to every minutes it works, but not the Push notifications.
I think I found the problem but not the way to solve it.
OSx Server needs to connect to Apple Push Notification services APNs.

I tried to set rules. Inside Firewall, WAN_IN but no succese. Do I need a WAN_OUT rule set?
