iOS裝置中per app vpn，到底需要哪些系統要求？

坑爹的Apple網站資料和MDM廠商資料，大多數說iOS 7.x裝置支援per app vpn了，但是沒有說明需要哪些系統內容要求。

1. iOS 7.x 裝置，當然了

2. iOS 7.x 裝置需在MDM伺服器上註冊並接受管理（MDM伺服器比如SAP Afaria（apple configurator可能也可以）可以下發專門的和per app vpn相關的MDM指令）

3.iOS 7.x 裝置要安裝vpn的用戶端。啥？不是內建VPN支援了嗎？對比起，這個per app vpn需要iOS裝置上面安裝特定VPN Client軟體啊

4. MDM伺服器：MDM伺服器比如SAP Afaria（apple configurator可能也可以）可以下發專門的和per app vpn相關的MDM指令

5.指定的VPN伺服器，不多。啥？iOS裝置支援的VPN不行？是滴，不是所有的都支援。

貌似Cisco AnyConnect, F5可以。

該文章介紹用AirWatch結合F5 SSL VPN配置per app vpn
The iOS Per app VPN uses F5’s APM SOCKS Proxy functionality so we'll need TMOS 11.4 or higher installed on the BIG-IP and Edge Client 2.0 or higher installed on the mobile device.

SAP Afaria論壇中的文章提到Cisco Anyconnect, F5支援Per App VPN，然後iOS裝置內建的vpn client不支援這個特性
"Per App VPN" requires additional VPN software to be installed.
Mocana, Cisco Anyconnect, F5, etc can do Per App VPN. The built-in VPN client doesn't do per-app.

某不知名的MDM廠商倒是明確說F5 Edge client and the Aruba VPN client支援per app vpn特性
I have applied a "Per app VPN" profile for iOS and deployed it. But the app does not use it. Why not?
The "Per app VPN" feature does not support the built-in VPN functionality as provided in iOS. Therefore, you cannot use this one.
What is required so successfully use it?
You must have installed a VPN client on the iOS device which supports the "Per app VPN" feature like the F5 Edge client.
If this is installed, you must deploy a VPN configuration for this client and in addition specify the VPN profile to be used by the app.
Which VPN Client does Sophos Mobile Control currently support?
As of now the only VPN client being supported is Cisco AnyConnect
Which VPN Clients do support the "Per app VPN" feature?
In december 2013 the only VPN clients supporting this feature are the F5 Edge client and the Aruba VPN client.
