Hi
On client side, do you have your network card connected to a physical network ? (to make the "Link" comes up, and then be able to publish you local route)
If no link is detected, the route won't be published.
I had the same problem using a 3G card. I found an issue using a virtual network adapter. (the link is always "UP", so the IP is allways published thru the VPN).
You can find it here.

You just have to configure the IP / Mask. No gateway needed
