Hi,
I know IOS clients need a stable and direct connection to apple's APNS servers(refer to If you're not getting Apple push notifications - Apple Support). But if I use a network which could not reach to internet unless I connected to a VPN, how can I make APNS work? It's a real question in some cases. I don't know why apple doesn't allow those traffics re-routing to VPN. Maybe for security reason. But I think if give a choice (like options) for end user is better.
Does anyone have same problem or solutions?
