思科路由静态NAT配置

Posted 2020-10-20

实验名称：思科路由静态NAT配置
实验拓扑：
实验环境：1、3台路由器，
2、一台交换机
Router 0 边界路由器（内网和外网）
Router 1 边界路由器（公网的内网和外网）
Pouter 2 内网路由器 （公网的内部网络）
3、一台PC

实验步骤：
1、 配置PC机地址：
IP ： 192.168.10.1/24
网关：192.168.10.25
2、 配置Router 0
Continue with configuration dialog? [yes/no]: n

Press RETURN to get started!
