This has been driving me crazy for days now...I've read so many FAQs, guides and forum posts that I've lost count.

In a nutshell, I want to share my DSL connection on my main WinXP (SP2) desktop to another PC via ethernet AND to my Tungsten T3 via Bluetooth.

In the Network Connections folder, both the Bluetooth LAN Access server and the Ethernet card are bridge to XP's Network Bridge. The Network Bridge is set to 192.168.0.1. The other ethernet-connected PC can access the net perfectly, but the T3 cannot.

I know the T3 is configured ok, because if I remove the Bluetooth LAN Access server from the Bridge, set the Bridge to a different address, and set the BT LAN Access server to 192.168.0.1, I can surf the net on the T3.

In case it matters, the Bluetooth driver is Widcomm v1.4.3 Build 4.

I guess this is an XP or IP configuration problem, rather than Bluetooth, but I'll listen to any good advice I can get.

The T3 needs LAP (LAN Access PPP). This is provided by your Bluetooth adapter when using "Share Internet" option. To allow sharing to more than one device you'll have to play with Bridge on your Windows XP.

Also, if you remove ICS the PPP will not work.

One option is to use MochaPPP, it works really wel...

Thanks, Mauricio.

I think this is the best approach, but I've tried everything I can think of.

I'll have a look at MochaPPP, but won't the speed be limited by the serial port driver?

MochaPPP will give the T3 the same speed as the native PPP driver over serial...

I found an easy solution without any additional software:

It seems that to make XP's network bridge work with WIDCOMM's BT LAN Access server, you need to force promiscuous mode compatibility.

Specifically, I did a 'netsh bridge show adapter' to get the id of the bluetooth network and then 'netsh bridge set adapter 1 forcecompatmode=enable'. See Microsoft KB article 302348 for more details.

Hmmm. Good spot. As the article says, not needed for all NIC - I'm using Windows XP Pro and didn't have to do this.

I'm also using XP Pro, with SP2. It was just a lucky spot.
