路由器NAT映射

1、搭建实验环境，进行NAT映射测试，将内部服务器192.168.160.53映射为10.38.200.18，具体拓扑如下：

2、R1：

interface FastEthernet0/0

 ip address 10.38.191.38 255.255.255.252

ip route 10.38.200.18 255.255.255.255 10.38.191.37

R2:

interface FastEthernet0/0

 ip address 10.38.191.37 255.255.255.252

 ip nat outside

interface FastEthernet1/0

 ip address 192.168.164.65 255.255.255.252

 ip nat inside

ip route 0.0.0.0 0.0.0.0 FastEthernet0/0

ip route 192.168.160.53 255.255.255.255 192.168.164.66

ip nat pool aaa 10.38.200.18 10.38.200.18 netmask 255.255.255.0

ip nat inside source list 1 pool aaa

access-list 1 permit 192.168.160.53

R3:

interface FastEthernet0/0

 ip address 192.168.164.66 255.255.255.252

ip route 0.0.0.0 0.0.0.0 192.168.164.65

做NAT时需要，ping或者访问流量激活后才有转换项：sh ip nat trans

在R2上：Debug ip nat查看具体NAT转换信息
