Bluetooth Network Connection not listed on Internet Sharing tab

Hi all,
I'm trying to share an Internet connection via bluetooth.

The host:
HP 8740w laptop running Windows 7 Enterprise x64
Connected to the Internet via Local Area Connection (wired)

The client:
Asus Transformer tablet

I have a bluetooth PAN setup and the devices are communicating properly. They both have IPs in the 192.168.44.x range, can ping each other, and I can use a Remote Desktop client on the tablet to control the PC.

The last piece I'm missing is giving the tablet access to the PCs Internet connection. I go into Network and Sharing Center, click Change Adapter Settings, and open the properties of Local Area Connection. On the Sharing tab, I check Allow other network users to connect through this computer's Internet connection. I then click the Home Network Connection dropdown, and Bluetooth Network Adapter is not listed. I see others, including my wireless card, VMware virtual adapters, VPN adapters, etc..

I've looked at the Bluetooth Network Adapter's properties, and it doesn't seem to be missing any protocols that the other adapters have. It's enabled, connected, and working fine locally.

Any ideas? Is there a registry hack or something that I have to do to make it show up in the ICS list?

Thanks!

try to put both ends of bluetooth to "dynamic ip" not a fixed ip address!! Not sure this will fix your problem.

Tried that, didn't help. My original config actually had the PC set to obtain IP automatically, and the tablet handing out DHCP. I know that's opposite what I want, but I set it up that way to test device to device connectivity since I couldn't get the PC to share (and thus hand out DHCP).

Any other thoughts?
