华为防火墙USG6000通过WEB图形界面配置案例

网络拓扑图

通过WEB方式登录到防火墙

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

• PC1
  
• FTP-Server
