PfSense as EXCLUSIVE L2TP/IPSec PSK server

[riahc3]

Ive tried using my router as a L2TP/IPSec PSK server: Could not get it to work.
Ive tried using my Windows Server 2012 R2 (which is also a DC and a DHCP server) as a L2TP/IPSec PSK server: Could not get it to work.

So Im gonna go with a trusty choice: Setup pfSense in a ESXi VM to use as a L2TP/IPSec PSK server.

This pfSense will be used for NOTHING else (no firewall, no routing, etc.). It should be able to assign the VPN client a IP from the DHCP pool in the Windows Server 2012 R2. so it can use all LAN resources. I have no intrest in using the internet thru the VPN.

The clients I will use are Android and Windows 7.

I was able to configure pfSense as strictly a L2TP/IPSec server but Im not sure how to integrate it into my network correctly.
