好的，所以我遇到了 Cisco PIX515 的一些麻烦，我已将当前运行的配置发布在下面，现在我绝不是思科专家，尽管我可以用它们做一些基本的事情，现在我在从外部发送到地址的流量时遇到了麻烦：10.75.32.25 它似乎没有去任何地方。
现在，这个防火墙位于私有网络深处，有一个我们无法管理的上游防火墙。我与负责该防火墙的人交谈过，他们说他们有流量路由到 10.75.32.21 和 10.75.32.25，仅此而已（尽管有一个网站从服务器 172.16.102.5 运行，如果我的理解正确的话，该网站通过 10.75.32.23 获得流量。
任何想法都将不胜感激，因为对我来说它应该都可以工作，但事实并非如此（显然，如果配置全部正确，那么我们尝试访问的 10.75.32.25 上的 Web 服务器可能有问题，尽管用户说他们可以从内部访问它（172.16.102.8），这更令人困惑）

事实证明配置很好，服务器响应虽然非常慢并且断断续续。
