Our VPN is not listed as a configurable option but I know iOS supports it? L2TP and IKEV2

Question

How do you go about setting up a VPN profile that uses L2TP to authenticate? Or IKEV2 (our secondary VPN). 
 I see no option in the GUI on SMC 6 apart from IPSEC and a few others we do not have. O 
 The devices are iOS 9 and the server is the latest version of SMC 6 hosted as a service by Sophos. 
 I have tried setting up the settings using the apple iphone configuration utility and then importing the outputted profile but that fails to transfer to our devices (error: "Completely failed"). 
 Thanks all!

You can try:

In order to successfully deploy a VPN profile follow these steps:

If the VPN configuration is part of a complex profile it is recommended to exclude this and make a separate profile for VPN

In the Sophos Mobile Control (SMC) web console go to 'Profiles | Apple iOS'

Press the magnifier icon next to the VPN profile in question to show the profile

Press the 'Download' button to export the profile and save the profile at a location of your choice

Open the profile using a text editor e.g. Notepad

Search for 'Proxies'

Remove the lines
'<key>Proxies</key>
'<dict>'
'</dict>'
Depending on the profile, the lines which have to be deleted might just be

'<key>Proxies</key>'
'<dict/>'

Save the changed file

In the SMC console go again to 'Profiles | Apple iOS'

Press the 'Import' button and upload the changed profile

After saving the profile, it should now be possible to deploy it.
