网络地址转换NAT配置

1、配置Server-PT服务器IP：192.168.1.2子网掩码：255.255.255.0网关：192.168.1.1

2、配置计算机PC0IP :222.0.2.2子网掩码：255.255.255.0网关：222.0.2.1

3、配置路由器Router0Router>enRouter#conf tRouter(co艘绒庳焰nfig)#host R0R0(c泠贾高框onfig)#int fa0/0R0(config-if)#ip address 192.168.1.1 255.255.255.0R0(config-if)#no shutdownR0(config-if)#R0(config-if)#int s2/0R0(config-if)#ip address 222.0.1.1 255.255.255.0R0(config-if)#no shutdownR0(config-if)#clock rate 64000R0(config-if)#exitR0(config)#ip route 222.0.2.0 255.255.255.0 222.0.1.2R0(config)#

4、配置路由器Router1R1>enR1#conf tR1(config)#host R1R1(艘早祓胂config)#int s2/0R1(config-if)#ip address 222.0.1.2 255.255.255.0R1(config-if)#no shutR1(config-if)#int fa0/0R1(config-if)#ip address 222.0.2.1 255.255.255.0R1(config-if)#no shutdownR1(config-if)#R1(config-if)#exitR1(config)#ip route 192.168.1.0 255.255.255.0 222.0.1.1R1(config)#endR1#R1#show ip route

5、PC0测试：ping 192.168.1.2

6、R0>R0>R0>enR0#conf tR0(con酆璁冻嘌fig)#int fa0/0R0(con熠硒勘唏fig-if)#ip nat insideR0(config-if)#int s2/0R0(config-if)#ip nat outsideR0(config-if)#exitR0(config)#ip nat inside source static 192.168.1.2 222.0.1.3R0(config)#endR0#R0#show ip nat translationsPro Inside global Inside local Outside local Outside global--- 222.0.1.3 192.168.1.2 --- ---

7、PC0测试 Web浏览器 http://222.0.1.3

8、测试Router0 show ip nat translations
