VPN problem

I want to connect on my network with VPN from anywhere.
I want to use Windows VPN connection.
I have router Speedport w274v Type Ci, Firmware version: 09091601.00.039. I want to use DynDNS, but I have problem with configuration.
On Dyn.com I have opened user account and there I have newly created host with my public IP address.
On domain server (Windows Server 2012 R2), I installed Dyn Updater and added my user account. After that I connected on router and on router enabled Dynamic DNS, add my account and save this. On Windows Server I don't install any roles (RRAS or something like that).
Firewall on server and PC is temporary disabled.
Settings for port forwarding I didn't configure.
This is picture for configuration port fw:

On PC I created VPN connection. On Properties for this connection in tab Security I added:
Type of VPN: Automatic
Authentication: Allow these protocol... Microsoft CHAP Version 2 (MS-CHAP v2).
But VPN connection doesn't work.

Do you have any suggestion how can I use VPN and how can I connect to my network with use only what I have from equipment?
