说明：上例不推荐使用。
以www服务为例,除了3.1.1和3.1.2的配置,公网接口需要增加如下配置:[Router-Ethernet1]nat server global 202.1.1.2 www inside 10.0.0.2 www tcp注意:如果需要其他用户可以ping通内部对外提供服务的服务器,必须增加如下配置:[Router-Ethernet1]nat server global 202.1.1.2 any inside 10.0.0.2 any icmp注意:内部用户不能使用公网地址来访问内部服务器,必须使用内网地址访问.如上例子:10.0.0.0/24网段的用户,不能访问202.1.1.2,而只能访问10.0.0.2
