VPN Forwarding not working

Hey
I am new with Zyxel Products.
I had a Netgear Firewall till yet. Behind my Firewall I have a Windows 2008R2 running a RAS Server (VPN)
It was not a Problem to connect with my VPN Server yet, but since my new Zyxel, it isn't working anymore...
What I did so far:
I created a Service Group and added the predefined Services:

Then I addes an address to my VPN Server:

And then I added a NAT

But the VPN can't connect
What am I doing wrong? - As I said, as I used the Netgear, everything was working fine.
I have other NAT's installed to connect to a service, this is working fine...
Hope someone can help me to identify the problem
THX

Seems, that I found the Problem.
On the NAT I have had to enable the NAT loopback Option - now everything works fine!

The firewall will not auto open for NAT mapping ports/protocol.
You need to add one security policy to allow the access,
From WAN ZONE to LAN ZONE,
Source: any, Destination: server IP address, Service: service group you use in NAT rule
Action: allow

Oh -sorry, yes I have this Policy already.
I have played around and I have renamed the service Group, because it had the same Name as the NAT entry. I thought, Maybe this could be the Problem, but it isn't...
I am running the program port query to check it, but it isn't working...
