我正在使用 ASDM，现在整个网络中没有人可以上网，有 AsusWireless（无线路由器）为人们分配了 IP 地址，例如 192.168.1.X，这些人、直接连接到 Cisco ASA（172.16.1.X）的人以及通过 AnyConnect（172.16.16.X）连接的人都无法上网。根本没有互联网。但是当我进入 Cisco 路由器的 ssh 并 ping Google 服务器时，它已连接并且有互联网。出了什么问题？我做错了什么？
答案1
快速浏览一下：
global (outside) 1 interface
nat (inside) 0 172.16.1.0 255.255.255.0 outside
nat (inside) 0 AsusWireless 255.255.255.0 outside
对象的 ID 不同（0 和 1），请尝试：
global (outside) 1 interface
nat (inside) 1 172.16.1.0 255.255.255.0
