QNAP威联通网络莫名断开备忘

问题描述

突然发现通过cf的tunnel访问的威联通nas无法访问了，通过ssh登录nas发现网络断开，ping不通外网，但是内网可以ping通。

解决方法

上网随便查了下，手动添加了网关，问题解决。
不知道重启后会不会有问题，暂时记录下。

    缺失模块。
    1、请确保node版本大于6.2
    2、在博客根目录（注意不是yilia根目录）执行以下命令：
    npm i hexo-generator-json-content --save

    3、在根目录_config.yml里添加配置： 

      jsonContent:
    meta: false
    pages: false
    posts:
      title: true
      date: true
      path: true
      text: false
      raw: false
      content: false
      slug: false
