Bridge Server on Windows XP
This configuration requires Windows XP or higher on the bridge side. To my knowledge, Windows 2000 does not support bridging, however a Windows 2000 machine can be a client on a bridged network, where the other end of the OpenVPN connection where the bridging is occurring is a Linux or Windows XP machine.
When OpenVPN is installed on Windows, it automatically creates a single TAP-Win32 adapter which will be assigned a name like "Local Area Connection 2". Go to the Network Connections control panel and rename it to "tap-bridge".
Next select tap-bridge and your ethernet adapter with the mouse, right click, and select Bridge Connections. This will create a new bridge adapter icon in the control panel.
Set the TCP/IP properties on the bridge adapter to an IP of 192.168.8.4 and a subnet mask of 255.255.255.0.
Next, edit the OpenVPN server configuration file to enable a bridging configuration.
Comment out the line which says dev tun and replace it instead with:
dev tap
dev-node tap-bridge
Comment out the line that begins with server and replace it with:
server-bridge 192.168.8.4 255.255.255.0 192.168.8.128 192.168.8.254
If you are running XP SP2, go to the firewall control panel, and disable firewall filtering on the bridge and TAP adapters.
At this point, the bridging-specific aspects of the configuration are complete, and you can continue where you left off in the HOWTO. |
