Well that sounds to me like your problem. Typically a VPN connection
will create a new "virtual" networking device and that will have an IP
address on the network you're connecting to, and will be added to your
route table as the device to connect to that network on. It sounds to me
like this step isn't happening - I'm not sure if that's because the VPN
device works differently in your case, or it's the actually problem. 

I'm actually with the author of this article so I can ask him a little
about how it works and see if he has any suggestions for you.
