到底防火墙有必要要那么专业的设置吗？网吧应用
刚开始做ROS，潜了一个月水，从不会到会做，只是停留在会做。还不能灵活应用ROS的强大功能，我的网吧是200来台机器电信+网通双线策略，什么都做好了，就差最后防火墙策略，在网上收集很多资料，也看了很多帖子，但就是理不出一个思路来，防火墙这边网吧除了要禁P2P，防止外网登陆外别的有必要要那么复杂的设置吗？搜集很多好心人提供的防火墙策略，实在是不敢用，不敢往上加，现在看运行情况，一直很稳定，没有出现什么异常。再看看论坛的防火墙方面的帖子，有很多有关防火墙方面出现的问题，所以大家可不可以给出个解释，在不影响速度和稳定的前提下，有没必要设置专业防火墙？如果有我应该从那方面着手？ 不是有必要，是相当有必要了！ 有必要，如果你不想内网设置太麻烦的话 ，可以不开WINXP的防火墙，用ROS把大部分的病毒和网上攻击给挡住，再加个还原卡，有问题重新启动就能解决了，否则每个机器玩的游戏端口都不一样，每个去搞的话烦死你
我在这里顶一下！目的是进来讨论一下！
我也刚学会做ROS！防火墙这方面就是里不出个头绪来！ P2P不用禁,做个整体限速就可以了,我的防火墙规则是/ ip firewall filterad ch input pr tcp dst-po 82 act drop comm Worm.NetSky.Y@mm

用到现在不错,for 2.9.6 我一条规则都不用，一样设置都不用，可能拖的少吧，反正，我自己开了20台机子，分别同时用迅雷下了三个热门软件。OFFISC2003 2007 CAD2006 跑到85M,其他人照样上网，看电影，聊天，下载，呵，再增了几台也没事，哈哈 还是加上好！我同意辉哥得想法！ 死搬硬套
不起作用! 没有必要的,因为很多网游使用很多端口,设置太多会影响网游更新.最重要的是不能禁止P2P下载 上边的防火墙,说它专业的是你根本就没有理解iptables的input .output,forward,三个链的区别,
至于其它的,我不想说多,
如果你非要说是mikrotik的路由里边就是那样的话,我只说你是死搬硬套,没有作用!
