How to use netcard simulations of SkyEye in Windows

SkyEye can offer netcard simulations in Linux by loading tun.o module. But how can it offer netcard simulations in Windows?
There are always two ways to use SkyEye in Windows. The first way is in Cygwin environment, which offers a Linux virtual environment on Windows. But it seems that there is no device in Cygwin environment. So it is hard to simulate netcard by it.
The second way is to compile SkyEye in MinGW environment. After that, SkyEye can run without any dlls in Windows. As it runs in no dependce of other virtual machine, so it speeds up the simulations. Then, a question come out, how can SkyEye compiled by MinGW simulate netcard?
Through analyzing the source code of SkyEye, we can find something useful in Skyeye_net.c. In MinGW environment, SkyEye can offer netcard simulations by installing TAP-WIN32 device, which supplied as a groupware in VPN install packages.
The installing steps is as follows:
1. Download OpenVPN install package, just need to choose to install TAP-WIN32 groupware in install guide.
2. After that, you will find there is a new network connection shows on desktop.Which displays TAP-WIN32 Adapter.
3. Double click the network connection you are using. You will find there is a properties setting about share of internet connection in properties->High. Choose both of the options. Select the TAP-WIN32 device in home network connection. Then click OK.
4. Now you can find that the IP and MAC of TAP-WIN32 connection is set automatically.
5. Then you can run the testsuite supplied by SkyEye, and use the netcard simulations of SkyEye.
