本文为大家介绍一个H3C防火墙的配置实例,配置内容包括:配置接口IP地址、配置区域、配置NAT地址转换、配置访问策略等,组网拓扑及需求如下。 1、网络拓扑图

2、配置要求

1)防火墙的E0/2接口为TRUST区域,ip地址是:192.168.254.1/29; 2)防火墙的E1/2接口为UNTRUST区域,ip地址是:202.111.0.1/27;

3)内网服务器对外网做一对一的地址映射,192.168.254.2、192.168.254.3分别映射为202.111.0.2、202.111.0.3;

4)内网服务器访问外网不做限制,外网访问内网只放通公网地址211.101.5.49访问192.168.254.2的1433端口和192.168.254.3的80端口。 3、防火墙的配置脚本如下 dis cur #
