ip地址不够用怎么办

1、//配置Router01

Router01>enable

Router01#configure terminal

Router01(config)#interface fastEthernet 0/0

Router01(config-if)#no shutdown

Router01(config-if)#ip address 192.168.1.1 255.255.255.0

Router01(config-if)#exit

Router01(config)#interface serial 2/0

Router01(config-if)#ip address 192.168.10.1 255.255.255.0

Router01(config-if)#clock rate 64000

Router01(config-if)#no shutdown

Router01(config)#ip route 192.168.11.0 255.255.255.0 192.168.10.2

Router01(config)#interface fastEthernet 0/0    

Router01(config-if)#ip nat inside

Router01(config-if)#exit

Router01(config)#interface serial 2/0    

Router01(config-if)#ip nat outside

Router01(config-if)#exit

Router01(config)#access-list 1 permit 192.168.1.0 0.0.0.255

Router01(config)#ip nat pool napt 192.168.10.1 192.168.10.1 netmask 255.255.255.0    //定义地址池（始IP，终IP）

Router01(config)#ip nat inside source list 1 pool napt overload                //映射地址池

Router01#write

2、//配置Router02

Router02>enable

Router02#configure terminal

Router02(config)#interface fastEthernet 0/0

Router01(config-if)#no shutdown

Router02(config-if)#ip address 192.168.11.1 255.255.255.0

Router02(config-if)#exit

Router01(config)#interface serial 2/0

Router02(config-if)#no shutdown

Router01(config-if)#ip address 192.168.10.2 255.255.255.0

Router02(config-if)#exit

Router02(config)#ip route 192.168.1.0 255.255.255.0 192.168.10.1

Router02#write

3、//测试：

//PC01访问，http://192.168.11.101

Router01#show ip nat translations

tcp 192.168.10.1:1031  192.168.1.101:1031 192.168.11.101:80  192.168.11.101:80

//PC02访问，http://192.168.11.101

Router01#show ip nat translations

tcp 192.168.10.1:1026  192.168.1.102:1026 192.168.11.101:80  192.168.11.101:80
