删除原路由
route delete 0.0.0.0
为外网添加静态路由
查看外网网关：假设为192.168.70.0
route add -p 0.0.0.0 mask 0.0.0.0 192.168.70.0
为内网添加静态路由
查看内网网关：假设为10.121.132.126
route add -p 10.0.0.0 mask 255.0.0.0 10.121.132.126
假如访问的网段是10.121.0.0 那么route add -p 10.121.0.0 mask 255.255.0.0 10.121.132.126
假如访问的网段是10.121.132.0 那么route add -p 10.121.132.0 mask 255.255.255.0 10.121.132.126
外网添加时子网掩码（mask后面的ip）一定要对应
10.0.0.0 -> 255.0.0.0
10.121.0.0 -> 255.255.0.0
10.121.132.0 -> 255.255.255.0
