:: 添加端口映射
netsh interface portproxy add v4tov4 listenport=80 listenaddress=0.0.0.0 connectport=8081 connectaddress=127.0.0.1

:: 查看所有映射规则
netsh interface portproxy show all

:: 开放防火墙
netsh advfirewall firewall add rule name="HTTP_80" dir=in action=allow protocol=TCP localport=80

:: 测试映射是否生效（在服务器本地执行）
