网络构建问题

lijianwei652

小弟在校学生，学习网络专业，如今淘得cisco1812路由器一台。宿舍有台式机做服务器，上网方式为联通ADSL 4M。现在拨号和动态域名的问题已经解决掉了，内网有七台电脑通过PAT方式的NAT可以访问外网。
cisco1812这台路由器有2个路由以太网口和八个交换以太网口。（八个以太网口不能配地址）
想把内网服务器的80端口映射到外网的80端口，求教怎么做！
现在配置如下：
R1#sho run
R1#sho running-config

做静态NAT映射 ip nat inside source static tcp * 80 * 80

我这里是ADSL拨号上网，地址会变的，我用的ip nat inside source static tcp 192.168.1.1  80 interface dialer0 80，但是没有成功。。。。
