H3C NAT配置实例

    

H3C NAT配置：

1、 配置静态地址转换：

一对一静态地址转换：[system]   nat static ip-addr1 ip-addr2 

静态网段地址转换：  [system]   nat static net-to-net inside-start-address inside-end-address global global-address mask

应用到接口：        [interface]nat outbound static

2、多对多地址转换：[interface]nat outbound acl-number address-group group-number no-pat

3、配置NAPT：[interface]nat outbound acl-number [ address-group group-number ]

两个特殊的NAPT：

Easy IP： [interface]nat outbound acl-number (转化为接口地址)

Lookback：[interface]nat outbound acl-number interface loopback interface-number (转化为loopback地址)

4、双向地址转换：[system]nat overlapaddress number overlappool-startaddress temppool-startaddress { pool-length pool-length | address-mask mask } (需要结合outbound命令)

5、配置内部服务器：[interface]nat server

6、地址转换应用层网关：[system]nat alg (专门针对ftp之类对NAT敏感的协议)
