如果有人手工设置IP在你的范围内，应该也是可以上的吧
好象DHCP本身没有这样的限制功能。

I am using DHCP to share private IPs with 20 clients. For the security reasons, I also addon the MAC identification via authorization. That is to say, ONLY the registered MACs can use the DCHP server, www, ftp and all other internet services.

不是的。可以设定DHCP服务器用MAC来验证对方的机器，如果是“事先登陆”的MAC， 则允许给其发放IP, 也就是允许对方上网。如果发现向DHCP服务器发出IP请求的机器的MAC不在“事先登陆”的MAC列表中，则拒绝发放IP,对方无法取得IP,自然无法上网。

如果他知道你IP范围，自己设置IP，你会有什么办法吗？
不妨试一试。

你如果想阻止某些计算机上网，和DHCP的使用是两码事。DHCP是为了方便局域网计算机的使用，和安全方面没有太大关系。

如果你向对上网用户进行管理，可以使用iptables，将“事先登陆”的用户MAC通过（pass），其他的MAC一律阻止(Block)。有关iptalbes的详细设定方法，可以查一下以前的精华贴。

其实block MAC也没有什么用的。
linux下一个ifconfig ether就可以把MAC改掉 ;)

If I can type chinese, I would be very glad. But fcitx and xcin never work, I tried many times, but .......
So not that I don't like type chinese. Please forgive me.

I am in univ, we use static ip address delievered by our univ(using DHCP). But we have to pay a lot of money as metioned above. So, we decide just apply one ip address. and use my computer as a servier. I think many poeple did that before:p :p :p :p :p :p
