只是尝试在 Cisco 887VA 上进行一些端口转发，结果发现这很麻烦。我尝试将 8080 等端口转发到互联网接口
首先，我要说的是，我一直在浏览这个地方和许多其他支持论坛，但出于某种原因，无论我得到什么解决方案，它似乎都不适合我。我在这里和思科支持论坛上发现了一些问题。
最烦人的是，我几乎 100% 确定这是最简单的事情。
事情是这样的。我有一台 Cisco 887VA，负责将我的 VDSL 连接路由到一个 VLAN。它还支持 DHCP，但仅此而已。我当前的拓扑只有一个主机直接连接到板载交换机端口。
这是配置；我希望有人能帮忙:)
仅供参考：它有 C880 V15.1(4)M4 Universal-K9

答案1
事实证明，我尝试进行端口转发的网络上主机丢失了其 IP 地址和网关。
nat 似乎运行良好。抱歉给您添麻烦了。
再次感谢你，战术。
