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
