只有一台电脑是LINUX系统！
具体到哪里设，我也不大清楚！
其它电脑只能上一些开放的网址！
我想不通的是为什么我把我的IP加到/ETC/SYSCONFIG/IPTABLES里也还要出现一个密码
只有服务器是Linux，你自己的机器呢？
你现在动的是Linux服务器？请将iptables -L的结果贴出来。

我在吃饭，等会儿回复。
q我们的不是LINUX系统
当前的iptables配置没有什么特殊，对内网机器都是一视同仁的，重点是要检查客户机的配置。
你要配置的IP为192.168.8.72的机器用的是什么版本的windows，以及什么网络登录方式？顺便将网络属性全贴出来（包含工作组或域、计算机名，是否登录到域及域的名称等，能写上的全写上）。
我的是xp 网关是192.168.8.253和192.168.8.19(这个在拔号器上)
计算机名是hejinjin
工作组是retnt
域是sziric
局域网里的设置是这样的192.168.8.253端口是3128就这么多
你的XP是域登录的方式联入网络，如果没有正确地输入帐号和密码那是无法访问网络的（包括本地网络和外部网络如InterNet的）。
但是他们的可以呀
