HCIA experiment (08)

1. To configure IP Address

[r1]int g0/0/0
[r1-GigabitEthernet0/0/0]ip add 12.1.1.1 24
[r1]int g0/0/1
[r1-GigabitEthernet0/0/1]ip add 192.168.1.1 24
[r2]int g0/0/0
[r2-GigabitEthernet0/0/0]ip add 12.1.1.2 24
[r2]int g0/0/1
[r2-GigabitEthernet0/0/1]ip add 1.1.1.1 24

2. by R1 Configure default pointing 12.1.1.2

[r1]ip route-static 0.0.0.0 0 12.1.1.2 

（ verification ）

（ It can be concluded that ,R1 Of G0/0/0 Interface is public IP）

3.“ One to many ”

[r1]acl 2000
[r1-acl-basic-2000]rule permit source 192.168.1.0 0.0.0.255
[r1]int g0/0/0
[r1-GigabitEthernet0/0/0]nat outbound 2000

（ verification ）

4. Port mapping

（1） Configure server

（2） Configure port mapping

[r1]int g0/0/0
[r1-GigabitEthernet0/0/0]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
[r1-GigabitEthernet0/0/0]nat server protocol tcp global current-interface 8888 inside 192.168.1.20 80

（3） test

4. Access one through the domain name server
