代码如下，实现的效果就是在几分钟内尝试登录多少次，就会自动封禁ip，24小时后解除（这个解除是触发器触发的时候进行检测的，所以只有下次登录的时候触发一下才能解除）
然后搜索 计划任务程序
创建一个计划任务，
在触发器里可以手动编辑xml，输入如下内容，可以根据你自己的需求来定义，
然后安装python，在操作里面选择启动程序，启动python如C:\Python39\python.exe ，添加参数如 D:\zixing\safe\secwall.py ，起始于如 D:\zixing\safe
其他配置根据你的需求来，然后就可以测试一下远程连接失败N次后是否会被防火墙屏蔽（当然前提是开了防火墙才可以）
