第一步，配置内网的ip地址
第二步，配置*的IP地址
第三步，配置一个ACL 包含容许上网的IP网段
第四步，配置NAT，把ACL翻译到*端口，并使用超载。

配置ACL
access-list 1 permit 192.168.0.0 0.0.0.255
配置NAT
ip nat inside source list 1 int XX overload
这里的int XX，是本地出口路由器与运营商连接的端口
指定outside
int xx
ip nat outside
这里的XX同上
指定inside
int yy
ip nat inside
这里的YY接口，是下联PC或LAN的接口（PC网关）
