一、实验拓扑: 二、实验要求: 实验一:Dinamic Identity NAT R1、R2都有默认路由,下一跳为ASA对应的接口地址。 实验二:Static Identity NAT 三、命令部署: 实验一: 1、清除上个实验的access-list: ASA(config)# clear configure access-list ASA(config)# show access-list

2、Inside内部署Dinamic Identity NAT使得10.1.1.1~10.1.1.100转换到Outside时,转换到自身: ASA(config)# object network in-yuan ASA(config-network-object)# range 10.1.1.1 10.1.1.100 ASA(config-network-object)# nat (inside,outside) static in-jing 验证: R2#telnet 202.100.1.1 Trying 202.100.1.1 ... Open User Access Verification Username: aa Password: R1> R1#show users Line User Host(s) Idle Location

实验二: 1、Inside内部署Statc Identity NAT使得10.1.1.2转换到Outside时,转换到自身:

ASA(config)# object network in-jing ASA(config-network-object)# host 10.1.1.2 ASA(config-network-object)# nat (inside,outside) dynamic in-jing

验证: R2#telnet 202.100.1.1 Trying 202.100.1.1 ... Open User Access Verification Username: aa Password: R1>

R1#show users Line User Host(s) Idle Location
