In this article we show how to configure and use your desktop or notebook with internet access as an internet gateway to another computer via Bluetooth.
For this we used a desktop running Windows 2000 Pro with a TDK USB Bluetooth (version 126.96.36.199) as a server. The client is a laptop running Windows 2000 Pro with a Bluetake USB Bluetooth (version 188.8.131.52). We assume you have already paired both computers. Do so before you continue following this guide!
Make sure your Bluetooth adapter support the LAN Access profile. Some products (like the 3COM) will not support this, while widcomm based dongles will have this functionality.
This guide is based on Windows 2000 machines. The dialogs for Windows XP might be a little different, but the configuration will be the same.
First, let's open My Network Places on the computer that will be the server on this configuration. You can do so by right-clicking the My Network Places icon and selecting Properties.
We want to change the properties for our connection to the internet. This is the adapter we want to share "from". Just right-click in the corresponding icon and select Properties.
The Bluetooth Network adapter was automatically created during the Bluetooth installation.
There's a bug in Windows 2000 before SP3 where changing the sharing option may change IP configurations in this adapter. To make sure you're safe, we will note the current configuration.
In the General tab select the Internet Protocol components and click Properties.
Write down all the information from the next dialog, and click Cancel.
Back in the Adapter properties, select the "Sharing" tab and tick "Enable Internet Connection Sharing for this connection".
Now, to configure the Bluetooth USB, right-click the Bluetooth icon in the system tray and select Advanced Configuration.
Change to the Local Services tab and double click "Network Access".
Change the type of service to "Allow other devices to acces the Internet/LAN via this computer".
The alternative to this option will allow your device to connect to your computer as part of a LAN, but will not have internet access.
Note the Configure Connection Sharing button: it'll open the configuration screens we've visited before. But some Bluetooth software will not have this button, hence I guided you through the other route .
On you client computer (in our case the laptop), open My Bluetooth Places. Double-click Entire Bluetooth Neighborhood to see all devices in your Bluetooth area.
Right-click the icon corresponding to the server. Select Connect Network Access.
The following dialog will show, while the connection is established. Tips: with older versions (1.2 and before) your might see a dialog asking for username and password. Simply hit the OK button. If this is the first connection between these computers, be prepared on the server computer to accept the connection and check the box "Do not ask me again".
Once the connection is established, a shortcut can be created. Double-click the icon corresponding to the server computer, and you'll see all services available. The Network Access will be highlighted in green, since it's currently active. Right-click the icon corresponding to this service, and select Create Shortcut. A shortcut to this connection will be created in My Bluetooth Places.
To disconnect, simply double-click this icon (or the shortcut created) and click the Disconnect button in this status screen:
