Mus,
The best way is to change your router and route all traffic thru the router. This will allow your PC, notebook, mobile phones and all users of that router access to netflix or others that are geo-locked.
But if you insist on using thru your laptop, you need to create a direct link between your computer and media player. Its like p2p between the two of them. Create a new network and put any public IP class as your IP on 192.x or 10.x or 172.16.x but make sure that the IP is not our IP or your router IP subnet.
If u put your notebook 10.0.0.1 then put 10.0.0.2 in wd-live. This way both of your pc and wd can see each other, except that now you are using your notebook as the gateway.
This setup has nothing to do with the VPN but once you setup the connection and allow sharing, all traffic requested by wd-live will go to the notebook which will then send it thru the vpn tunnel.
Hmm, lo, confusing? Call me
