Bluetooth reverse tethering

Hey all so I have connected my HTC to my laptop via Bluetooth ( they're paired and connected) - the Bluetooth Tethering option in the phone is Enabled - I can see a Bluetooth network connection has been added in network connections and adapter panel - I'm stuck after this.... - the problem is that when I go to the sharing tab of the network connection which I'm trying to share it's internet, there it asks you to select a network connection which the internet is going to be shared too but the Bluetooth connection wont show so I could select it...
