在win7环境下首先要提升WINDOWS命令行处理程序的运行权限（右键点命令行运行程序，选择以管理员权限运行即可）。
点击运行以下脚本。
其中10.3.X.换成自己外网的网关，11.247.4.X更换成内网IP,11.247.8.x 更换成内网网关就可以了。
@echo Begin delete old routes!
route delete 0.0.0.0
route delete 11.0.0.0
route delete 12.0.0.0
echo ...
echo Begin add new routes !
route add 0.0.0.0 mask 0.0.0.0 10.3.X.X -p
route add 11.0.0.0 mask 255.0.0.0 11.247.4.x -p
route add 11.0.0.0 mask 255.0.0.0 11.247.8.x -p
