华为防火墙USG6000:NAT和NAT Server配置案例
网络拓扑图
通过WEB方式登录到防火墙
通过Web方式登录USG6000V:教程
登录成功
配置防火墙使内网用户通过PAT方式上网
防火墙上新建一个Nat Pool,供内网用户以NAT方式访问外网
配置Nat策略
配置策略,使得trust区域可以访问untrust区域
配置默认路由,指向R1
设置到达Nat Pool的静态路由,指向一个空接口,防止路由黑洞
配置防火墙使得外网用户能访问企业DMZ区域的FTP服务器(双向nat)
先配置服务器对外静态映射
防火墙上配置一个策略,使得untrust区域能访问DMZ区域
配置nat pool地址池,目的是作为外网用户访问内网服务器后nat的内网地址
配置一个nat策略。注意,这个nat策略和内网nat外网有所不同!!!
最后配置一个到达服务器对外地址的静态路由,防止路由黑洞
WEB界面配置完成
内网用户与FTP-Server配置
