L2TP Site to Site VPN issues

I have a windows 2008 r2 server that needs to establish a VPN connection to a remote VPN server.

We're using the L2TP protocol with a pre-shared key.

I initially used the New Demand Dial interface wizard. Then I went into properties on the interface and set the type of VPn to L2TP/IPSec and put the key under the advanced settings.

The error I received when attempting to connect is:

An error occured during connection of the interface. A Demand Dial
Router attempted to connect over a port that was reserved for Remote
Access Clients only.
