I have to choose PAP as the only selected protocol for it to work.The last time I enabled other encryption protocols, in addition to PAP, the VPN would not connect.As a result I cannot connect my iOS device to the L2TP server. Then in Windows 10, create the L2TP VPN as usual, but change the adapter settings - Security, choose optional encryption, allow only PAP as data encryption protocol ( which is where it blows my mind). My DNS is from Comcast and you can of course use a different one.I have PFS disabled for whatever reason, not sure if it will work if I turn it on.

Phase 1 and Phase 2 are both Group 2/3DES/SHA1.

Just follow my IPSec and L2TP server examples. It probably will not be an option for your scenario, though. It took me some time to get L2TP working with Windows 10, and the configuration is somehow counter-intuitive.
