我从一位老同事那里得到了这台 Cisco 7301 路由器，我用它来练习 Cisco 的东西。现在我有一个测试网络设置，其中一个接口作为我的“WAN”，另一个接口带有子接口作为我的第 2 层交换机。
我想对子接口进行 NAT，但是在任何地方我都没有看到任何 IP NAT 命令！
我在 Google 上查找过，总是从其他问题和文章/博客中获得相同的 IP NAT 命令，但我似乎根本无法在该路由器上找到该命令。
还有人熟悉这个路由器吗？我不太清楚为什么这个命令在任何地方都无法识别。我检查了全局配置提示符、接口配置提示符。什么都没有……

我添加了access-list希望，希望它能够允许我的 VLAN 上的客户端进行 ping8.8.8.8操作，或者至少允许流量通过我的 ASA 到达互联网，但它没有起作用。
例子
我运行的示例命令是Router(config)# ip nat pool VLAN10 10.10.10.0 10.10.10.254 255.255.255.0
我得到的结果是：
Router(config)#ip nat pool VLAN10 10.10.10.0 10.10.10.254 255.255.255.0
^
% Invalid input detected at '^'
Router(config)#
无论我在哪里运行此命令，路由器都无法识别它。

答案1
您有一个服务提供商映像 (P)。该映像不支持 NAT 功能。您需要获取 IP 映像或企业映像。（c7301-is-mz 或 c7301-js-mz）
