今天咱们简单讲解一下内网服务器一对一映射教程，希望对您有所帮助。以下IP地址及映射地址均为举例说明。

内网服务器ip：192.168.1.1

内网网关ip：192.168.1.100

外网映射的ip:222.222.222.222

interface　f0/0

ip address 192.168.1.100 255.255.255.0

no shutdown

ip nat inside

interface f0/1

ip address 222.222.222.222 255.255.255.0

ip nat outside

no shutdown

ip nat inside source static 192.168.1.1 222.222.222.222

下面是以80端口为例，配置iP及接口设置一对一映射：

ip nat inside source tcp 192.168.1.1 80 222.222.222.222 80
