ippp0是什么东东？脚本里面看不了，也没有见过。。
不是 ippp0 是 ppp0。 哈啤猫，你转的这个脚本小弟有些地方不懂啊，给加人注释啥的吧！ 你先看看 IPTABLES的 资料，然后再看这个哦。此外少了些东西。。。。能理解结构就可以了，只是个参考。太长了，我就转了防火墙这部分，这个站点用SQUID做的反向代理。 呵呵,希望把整个防火墙都发出来看看,用文件传上来 对强烈建议!!!..... ppp0 应该是自定义的接口名称吧 $RED_DEV$ORANGE_DEV$GREEN_DEV
这几个变量的值是什么? 才发现这是个老贴.... 呵呵~ 喜欢老贴。 linux下IPTABALES的
ROS不合适用的
