Now if what I am about to ask about is better suited for a different VPN protocol, please let me know.
I am trying to set up the Cisco CSR1000v to be the only way into a private subnet. What I would like, is to set the CSR as the IPsec "server" that can be remotely accessed through all sorts of devices. iPhone, Android, Generic Routers, you name it, I want access with it. I would also like this access to be granted using a PSK. Is there documentation showing how to do this? I have followed the guide below, but it does not mention the use of a PSK.

If there is anything I could add to help figure this out, just ask.
