<p>然后开始验证三级代理是否建立成功，首先尝试代理并测试：</p>

<p>可能是因为代理服务器并不出网，处在内网环境的原因，所以直接尝试远程桌面连接：</p>

<p>测试通过，代理成功</p>
<h2 id="h2-6">总结</h2>
<p>使用frp有很多优势：</p>
<blockquote>
<p>1.利用处于内网或防火墙后的机器，对外网环境提供HTTP或HTTPS服务。</p>
<p>2.对于HTTP、HTTPS服务支持基于域名的虚拟主机，支持自定义域名绑定，使多个域名可以共用一个80端口。</p>
<p>3.利用处于内网或防火墙后的机器，对外网环境提供TCP和UDP服务，例如在家里通过SSH访问处于公司内网环境的主机</p>
</blockquote>
<p>对于其它穿透隧道工具的不足：</p>
<blockquote>
<p>1.Earthworm不能过杀软，秒杀</p>
<p>2.Tunnel非常不稳定，web都动不动就崩溃，更别说支持3389</p>
<p>3.ptunnel环境在内网多限制情况不可利用，局限性大</p>
<p>4.DNS隧道穿透，适合僵尸网络</p>
