NAT地址转换

一：实验环境 1.1： 华为ensp软件 1.2： PC机和路由器及交换机 初始化状态的PC机和初始化状态的路由器,交换机连接如图拓扑，并开启 二．实验需求，R2提供NAT服务;server页面访问 三：实验过程 3.1：配置SW1交换机

3.2配置AR1路由器 AR1配置 3.2.1 配置接口

[R1]int g0/0/0
[R1-GigabitEthernet0/0/0]ip add 11.0.0.1 24
[R1-GigabitEthernet0/0/0]un sh
[R1-GigabitEthernet0/0/0]int g0/0/1
[R1-GigabitEthernet0/0/1]ip add 12.0.0.1 24
[R1-GigabitEthernet0/0/1]un sh

3.2.2配置DHCP中继服务（指定中继路由地址）

[R1]int g0/0/1
[R1-GigabitEthernet0/0/1]nat static enable
[R1-GigabitEthernet0/0/1]q
[R1]nat address-group 1 212.0.0.100 212.0.0.200
[R1]acl 2000
[R1-acl-basic-2000]rule permit source 192.168.20.0 0.0.0.255
[R1-acl-basic-2000]rule permit source 11.0.0.0 0.0.0.255
[R1-acl-basic-2000]int g0/0/1
[R1-GigabitEthernet0/0/1]nat outbound 2000 address-group 1 no-pat
[R1-GigabitEthernet0/0/1]q
[R1]acl 3000
[R1-acl-adv-3000]rule permit ip source 192.168.30.0 0.0.0.255
[R1-acl-adv-3000]int g0/0/1
[R1-GigabitEthernet0/0/1]nat outbound 3000
[R1-GigabitEthernet0/0/1]nat server protocol tcp global 9.9.9.9 www inside 192.168.10.100 www
[R1-GigabitEthernet0/0/1]nat static global 8.8.8.8 inside 192.168.10.10

3.2.3配置静态路由

[R1-GigabitEthernet0/0/1]q
[R1]ip route-static 0.0.0.0 0.0.0.0 12.0.0.2
[R1]ip route-static 192.168.10.0 24 11.0.0.2
[R1]ip route-static 192.168.20.0 24 11.0.0.2
[R1]ip route-static 192.168.30.0 24 11.0.0.2

3.3 配置R2路由器 3.3.1配置接口

interface GigabitEthernet0/0/0
 ip address 12.0.0.2 255.255.255.0
interface GigabitEthernet0/0/1
 ip address 13.0.0.1 255.255.255.0
interface LoopBack0
 ip address 114.114.114.114 255.255.255.255

3.3.2配置路由

ip route-static 8.8.8.8 255.255.255.255 12.0.0.1
ip route-static 9.9.9.9 255.255.255.255 12.0.0.1
ip route-static 212.0.0.0 255.255.255.0 12.0.0.1

3.4 其他配置 3.5 检查是否满足需求
