NAT地址转换技术原理

步骤：PC1-PC4配地址

LSW1：v b 10 20 30 40   六接口accsee

静态NAT

进虚拟地址 配相应IP

 ip route-static 0.0.0.0 0.0.0.0 11.0.0.1

AR1:进两接口 配地址  开启

ip route-static 192.168.10.0 24 11.0.0.2

ip route-static 192.168.20.0 24 11.0.0.2

ip route-static 192.168.30.0 24 11.0.0.2

ip route-static 0.0.0.0 0.0.0.0 12.0.0.2

 

iint g0/0/1 nat static global 8.8.8.8 inside 192.168.10.10

R2:int g0/0/0 给地址

ip route static 8.8.8.8 255.255.255.255 12.0.0.1

R2: int loo 0 给地址

      int g0/0/2 给地址

ping 114.114.114.114

动态NAT

R1： nat address-group 1 212.0.0.100 212.0.0.200

acl 2000

rule permit source 192.168.20.0 0.0.0.255

rule permit source 192.168.10.0 0.0.0.255

int g0/0/1

nat outband 2000 address-group 1 no-pat

R2:ip route-static   212.0.0.0 24 12.0.0.1

Easy Ip

R1:acl 3000 

rule permit ip source 192.168.30.0 0.0.0.255

int g0/0/1

nat outband 3000

NAT  server

server 1 http server   D盘里用文档做个页面（ txt-html） 启用 

R1：int g/0/1 nat server protocal tcp global 9.9.9.9 www inside 192.168.10.100 www

R2：ip route-static 9.9.9.9 255.255.255.255 12.0.0.1
