实验拓扑

实验需求

1. 按照图示搭建拓扑并且配置IP地址
2. 在RTA上配置NAT Server
3. 私网到公网写一条默认路由
4. 在PCA上通过ping命令检查与Client-A的互通性

实验解析

1、配置IP地址

步骤1：配置Client-A的IP地址

步骤2：配置Client-B的IP地址

步骤3：配置RTA的IP地址

[RTA]interface GigabitEthernet 0/0
[RTA-GigabitEthernet0/0]ip address 10.0.0.254 24
[RTA]interface GigabitEthernet 0/1
[RTA-GigabitEthernet0/1]ip address 192.168.1.1 24

步骤4：配置RTB的IP地址

[RTB]interface GigabitEthernet 0/0
[RTB-GigabitEthernet0/0]ip address 192.168.1.2 24
[RTB]interface GigabitEthernet 0/1
[RTB-GigabitEthernet0/1]ip address 192.168.2.1 24

步骤4：配置PCA的IP地址

2、在RTA上配置NAT Server

步骤1：在出接口上将私网地址与公网地址做一对一映射

[RTA]interface GigabitEthernet 0/1
[RTA-GigabitEthernet0/1]nat server protocol icmp global 192.168.1.3 inside 10.0.0.1
[RTA-GigabitEthernet0/1]nat server protocol icmp global 192.168.1.4 inside 10.0.0.2

3、私网到公网写一条默认路由

[RTA]ip route-static 0.0.0.0 0 192.168.1.2

4、在PCA上通过ping命令检查与Client-A\Client-B的互通性

步骤1：ping Client-A映射的公网地址

<H3C>ping 192.168.1.3
Ping 192.168.1.3 (192.168.1.3): 56 data bytes, press CTRL_C to break

56 bytes from 192.168.1.3: icmp_seq=4 ttl=253 time=3.000 ms

步骤2：ping Client-B映射的公网地址

<H3C>ping 192.168.1.4
Ping 192.168.1.4 (192.168.1.4): 56 data bytes, press CTRL_C to break
