我可以通过外部 IP 访问本地服务器，但不能通过内部 IP 访问

我可以通过外部 IP 访问本地服务器，但不能通过内部 IP 访问

我在运行 raspbian 的 Raspberry Pi 上安装了 apache2。然后我配置了路由器，将端口 80 和 443 映射到 Pi 上的相同端口 (192.168.2.108)。

从我的 Pi 本身，我可以通过输入 localhost 或 127.0.0.1 或其本地 ip (192.168.2.108) 或我的路由器的外部 ip 来访问 apache 测试页面。

从我的笔记本电脑上，我只能通过输入路由器的外部 IP 地址来访问该页面，但是不是通过输入我的 Pi 的内部 IP (192.168.2.108)。

知道原因吗？以下是一些可能很重要的信息：

有趣的新信息：我可以使用 192.168.2.108 从我的智能手机访问测试页面！如果我使用 Chromium 而不是 Firefox，它也可以在我的笔记本电脑上使用。

谢谢你的提示，sinclair！这与代理无关。但当我搜索代理设置时，我发现了这一点Firefox 帮助页面并尝试了每一步。最后一个解决了我的问题：

我必须清除 cookies 和缓存。
