This is a small utility (driver and GUI configuration tool) for MAC level bridging TCPIP bound network Interfaces (based on NDIS-hooking technology for Windows 2000/XP/2003). It can be used, an example, with OpenVPN in its bridging mode, especially with the server-end running on a Windows 2000 machine (which misses native bridging available since Windows XP) or just for bridging wireless and wired Ethernet when IP address space can't be divided into subnets.
