A networking setup question(13.3k picture warning)

[teetee]

The reason why I try to go with this strange setup (diagram below) was because I couldn't get the wireless card(intel 2200bg) working under OS X on X41 tablet(PC#2 in the diagram) and the only possible option I can use to connect the tablet to the Internet wirelessly is through bluetooth, which works out of the box in OS X.

Here is the diagram:


What I am trying to achieve is to find a proper configuration to allow users at both PC#1(the windows 2003 server) and PC#2(PC or Mac) to use the Internet when the connection between PC#1 and PC#2 is Bluetooth PAN.

I guess I am dealing with two issues here, one is the bluetooth PAN settings and the other is the Internet Connection Sharing/NAT Router settings.

I noticed that after I installed the bluetooth software(IVT bluesoleil) on PC#1, the bluetooth adapter didn't get a IP address automatically(it has 0.0.0.0). So I assigned a IP address (192.168.122.1) on the bluetooth PAN on PC#1 ( the IP address is not shown in the diagram). After PC#1 and PC#2 are connected by PAN and Internet Connection Sharing is enabled on PC#1, I found out it didn't work as I planned (User from PC#2 couldn't get online).

I wonder if there is anything I missed here or maybe I am not doing things right.

Get another wifi-card.
Then let both PCs/laptops acquire their own IP and DNS, instead of giving them a fixed IP.
That's what routers/NAT are for.

Unfortunately X41 tablet has this strict white list thing that it only allows users to use intel 2200bg/2915abg cards(which there is no WEP-working OS X driver yet) and very few atheros AR5004X cards(which I don't even know if there is any driver for OS X) according to ltwbook.pdf and forum discussions in the past. While I am looking for one of those compatible atheros wifi cards I thought I might as well try to see if the BT+NAT method works(or not).

Try creating a bridge over the BlueTooth and (W?)LAN networks on the Win2003 machine, so that the bluetooth-connected computer can see router directly. I have connected my phone (K800i) to the router and to the net this way, too Though even the InternetConnectionSharing over PAN worked for me, but it needed some setup from drivers and I don't have the BlueSoleil ones.
