我有 Cisco 1812 路由器,我想将其设置为我们的办公室互联网网关。尽管我遵循了 Cisco 网站上的指南,但我无法让 NAT 工作。
我的问题是 NAT 没有发生,我不知道为什么。
当我连接到路由器时,我从 DHCP 获得 IP 地址,我可以 ping 本地接口 IP(192.168.210.254)和公共 IP(212.94.196.71 略有变化),但我无法通过互联网。我无法从连接到本地接口的机器 ping 默认网关,但我可以从路由器本身以及 Internet 上的任何站点 ping 它。
最后,show ip nat translations 显示空列表。
我究竟做错了什么?
这是我的配置
