H3C防火墙2区域配置案例
基于多年参与电力行业信息化的经验，H3C公司推出电力信息网络安全加固解决方案，该解决方案主要由对终端安全防护和安全管理中心等关键部件组成。那么H3C防火墙2区域是怎么配置的呢?下面跟yjbys小编一起来看看!
1、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。
2、防火墙的配置脚本如下
