Configuring global parameters:

Enter host name [Router]: Router (路由器取名为Router)

The enable secret is a one-way cryptographic secret used

instead of the enable password when it exists.

Enter enable secret: cisco (设置路由器高级口令为cisco)

The enable password is used when there is no enable secret

and when using older software and some boot images.

Enter enable password: user (设置路由器低级口令为user

测试了一下。在PC上用花生壳的客户端，动态域名解析能起作用。用路由的DDNS，解析不起作用。明显，小米未经花生壳认证，被封了。

先问运营商是不是公网ip（动态静态都可以），如果不是想办法跟他要，确定了是公网ip之后就去小米ddns里面填写信息。。。。本人建议使用花生壳（我家ddns用的就是花生壳），填写完之后等待页面显示连接正常的字样并确保是已开启状态，然后等待几分钟再用手机开流量访问你建的网站。
注意：因为国家政策，80端口（http）和443端口（https）运营商是默认封禁的，但是21端口没有封（ftp）。所以在服务器（计算机）那边一定要把端口改了，并且确保不与别的端口冲突。建议改成90端口（http）和440端口（https），我现在自己用的就是这两个端口。
