这似乎是一个 NAT 问题，但我完全不知道为什么它无法连接。
Cisco g0/0 192.168.42.5/24 <-> Wireless WAN: 192.168.42.1/24
Cisco g0/0 - shutdown
Cisco g0/2 192.168.41.1/24 <-> Computer: 192.168.41.29/24
设想：
我正在从 Cisco 2911 ping -> 41.1、42.1、42.5、41.29 以及 google.com，我正在从计算机 ping -> 41.1 42.5，但无法 ping 42.1 或 google.com
为什么我现在无法从计算机 ping 外部？为什么不允许来自 192.168.41.0 0.0.0.255 的流量过载 g0/0？:(

答案1
嗯，我明白了。我有no ip route，应该是ip route
也存在一些访问列表问题，但我能够运行它。
