VPN ID field is mandatory, why?
When creating a VPN profile for IOS, there is a field called "VPN Identifier (provided by VPN vendor)".
- why is this field MANDATORY (according to https://tools.ietf.org/html/rfc2685 as far as I understand, it should not be) ?
- VPN providers I contacted did not know what it was and they did NOT provide the ID. (ex. Microsoft Intune Hotline, Synology Helpdesk)
- Customer data following it isn't clear either...
Would it be very difficult and highly unprofitable to put a little more information next to each field in the forms (generally speaking)?
Hi, Thomas, I heard back from the PM who owns that and he said “VPN identifier is what iOS uses to call the appropriate app on the device to initiate the VPN connection. If VPN identifier is not provided, VPN connection is bound to fail because iOS won’t know which VPN app to open.”
If you want to cite a specific section the RFC I can take that back to him.

Hi Cathy. Thanks for the information. I understand now what that VPN identifier does.
I still would like to know how do YOU know that and what if I just want IOS to connect like it does now? I set up the VPN connections by hand on IOS's and there is no question about VPN identifier. It works fine. It does not use any fancy client software but the built-in one in IOS. The same is also true for the other VPN profiles where one has to choose among brands like F5, Cisco, dell *** or Sonicwall, but not a standard Microsoft server based VPN using native VPN client of the OS. Had to spend hours to make it work using OMA-URI to use PPTP/IKE-v2/L2TP/SSTP on Windows 10 clients. What a mess...
