I'm teaching myself how to set up Windows Server, and have managed to get my server set up basically how I want it (remote access, networking, etc), but realized I can't VPN into my Server/Network from my Lumia because WP8.1 seems to require IKEv2 by default and I am using PPTP with my Surface 2 with Server Essentials. It appears that the only way to configure it is with the Routing and Remote Access Management Console (rrasmgmt.msc), but that seems to be disabled now that I installed Windows Server Essentials 2012 R2.
I may be missing something, but if anyone has any suggestions I would really appreciate it.
