NAT实验（初学）

实验要求

实验拓扑图

 

实验步骤

一、配IP

[r1]int g0/0/0
[r1-GigabitEthernet0/0/0]ip add 192.168.1.1 24
[r1-GigabitEthernet0/0/0]int g0/0/1
[r1-GigabitEthernet0/0/1]ip add 12.1.1.1 24
[r2]int g0/0/0
[r2-GigabitEthernet0/0/0]ip add 12.1.1.1 24
[r2-GigabitEthernet0/0/0]int g0/0/1
[r2-GigabitEthernet0/0/1]ip add 1.1.1.5 24

二、缺省路由

[r1]ip route-static 0.0.0.0 0 12.1.1.2
[r1]dis ip routing-table

测试

三、端口映射

[r2-GigabitEthernet0/0/2]nat server protocol  tcp global current-interface 80 inside  192.168.1.10 80

Warning:The port 80 is well-known port. If you continue it may cause function failure.

Are you sure to continue?[Y/N]:y
