HCIA_ Nat experiment

Experimental questions

Topology

experimental analysis ：

1、 Only one public ip Need to pass through http Access to two servers , To do port mapping

2、 Access the server through the domain name , So we need one dns The server

Specific configuration content ：

R1:
[Huawei]sysname r1
[r1]int g0/0/0
[r1-GigabitEthernet0/0/0]ip add 192.168.1.1 24
[r1-GigabitEthernet0/0/0]int g 0/0/1
[r1-GigabitEthernet0/0/1]ip add 12.1.1.1 24
[r1-GigabitEthernet0/0/1]q
[r1]acl 2000  
[r1-acl-basic-2000]rule permit source 192.168.1.2 0.0.0.0
