                <p>国内的服务器除了挂个备案，不想再要了。而许多内网的服务需要在外网访问，内网穿透是必不可少的。但是用国外的服务器的话，需要过一层未知的东西，难免被误伤，融入汪洋大海也是必须的。之前折腾了一下通过套一层<a href="/Protocol-for-intranet-penetration-based-on-QUIC">QUIC</a>来伪装，不知道为什么，总是不稳定。寻寻觅觅，又找到一个特征少的内网穿透工具：<a target="_blank" rel="noopener" href="https://github.com/sazima/proxynt">ProxyNT</a> 。ProxyNT是一个用python编写的基于WebSocket的反向代理服务器，可以透过NAT和防火墙将本地服务器暴露到公网上，从原理看，套上一层CDN保护公网ip也是可以的。</p>
