问题描述：
在web上新增一个公网地址，需要任何地方局域网能访问到这个IP地址所属的服务器，目前防火墙上已经有一个同网段的公网地址了，如何设置能将新的公网地址放行，本人萌新，请大佬们可以讲细致些，万分感谢

您好，请知：
以下是防火墙将内网服务器映射到外网的参考案例：
组网说明：
本案例采用H3C HCL模拟器的F1060来模拟NAT server典型组网配置，内网和外网在网络拓扑图中已经有了明确的标识，FW1作为内网的出口设备，不仅保护内网的安全，也提供地址转换的服务。内网申请了202.1.100.2-202.1.100.3这两个公网地址，其中202.1.100.2用于FW1与外网互联使用。202.1.100.3用于给内网的WEB服务器转换并对外网提供WEB服务。由于模拟器及物理机的局限性，因此采用H3C HCL模拟器的S5820交换机开启WEB功能模拟成WEB服务器。
配置步骤
1、按照网络拓扑图正确配置IP地址
2、Web_server开启WEB功能，并创建相应账户及赋予权限
3、FW1配置NAT地址转换，并配置默认路由指向外网
4、FW1配置nat server，并发布内网的WEB服务器
配置关键点
