quit
quit
配置NAT和ACL
R1

acl number 2000
rule 10 permit source 192.168.10.0 0.0.0.255
interface GigabitEthernet0/0/2
acl 2000 inbound
quit
user-interface vty 0 4
acl 2000 inbound
authentication-mode password
123
user privilege level 15

第五步：進行驗證。

驗證PC自動獲取ip地址，且可以ping通server1服務器：

驗證Client1可以訪問Server1的www服務，但不可以ping通服務器

 至此項目配置并驗證成功。。。。。。
