电信到底是如何控制只让一台电脑上ADSL的？

我相信过不了多久相应的破解办法就会出来的，下一版本的宽带路由器和共享软件肯定可以用的。实在不行的话还可以安装一台WIN2000 终端，大家通过WIN2000终端共享上网算了。:cool:

迷惑，怎么可能做到。

也许是通过反向探测上网代理机器是否开代理服务！也许可以打开代理防火墙，把外网的任何非允许端口请求屏蔽。

For NAT, you cannot directly detect machines behind the NAT firewall through MAC/IP addresses! However, some information, e.g., TTL may reveal some information. Also, high-level protocol, e.g., HTTP may reveal some information. For example, if you use a Linux box as NAT, however, the user-agent of an out-going HTTP request is from an Internet Explorer, then you are pretty sure the Linux bos is a firewall/proxy.
