我已经用 DD-WRT 版本 V24-preSP 2201412-22-2014-r25697 刷新了 ASUS AC-RT56U 路由器。现在我想用 wifidog 将其变成热点，放在小型企业（健身中心）中
我创建了自己的身份验证服务器，以排除故障。当我连接新的无线设备时，它无法访问互联网，只能访问 DD-WRT 路由器和身份验证服务器。当我输入 URL（例如：www.google.com）时，我不会被重定向到登录页面。在服务器上的 access.log 文件中，我只看到 DD-wrt 路由器向服务器发送 ping 请求。我有它，所以我的自定义身份验证服务器总是回复“Pong”。
我发现这里有一个 bughttp://svn.dd-wrt.com/ticket/3344。但它没有任何回应。这正是我的设备上发生的情况。当我访问 http://routerip:2060 时，我确实得到了我的身份验证服务器的门户页面。
现在我想知道是否可以创建一个 iptables 规则，以便所有未经身份验证的流量都重定向到 http://routerip:2060 页面？我猜当重定向有效时，其余过程就会有效。
这是 wifidog 身份验证过程的示意图。第一个重定向不起作用。 http://dev.wifidog.org/wiki/doc/developer/FlowDiagram
我没有修改 iptables 规则的经验。

答案1
这是 DD-WRT 的一个错误，它基本上无人维护和支持，并且已经存在多年了。
您的选择是使用没有此错误的其他东西（理想情况下是积极开发和维护的东西），或者忍受此错误。
