╃苍狼山庄╃内网穿透动态域名解析服务（简称NAT-DDNS），是一种基于动态域名服务（DDNS）和网络地址转换（NAT）的服务器内外网动态映射方法。
帮助用户实现在内网IP地址环境下也能实现动态域名解析服务，使动态IP地址实时与服务器保持交流，绑定固定域名，让上网用户输入特定域名即可访问内网主机，轻松实现用自己的主机架设WEB/FTP/OA/ERP/CRM等服务器，还可实现远程管理、远程存取等功能。
在此非常感谢koolshare的宝大对ngrok进行的二次开发。
脚本是业余爱好，英文属于文盲，写的不好，root帐号登录你的vps执行下面命令：建议先安装screen。
安装命令执行：
wget --no-check-certificate https://github.com/clangcn/ngrok-one-key-install/raw/master/install_ngrok.sh -O ./install_ngrok.sh chmod 500 ./install_ngrok.sh ./install_ngrok.sh install
