555,我的网关还是没搞定!
发现没有/etc/sysconfig/iptables文件,用gugong兄的样例改了一下,放了一个过去,然后/etc/rc.d/init.d/network restart,没有用,还有报错信息,现在我不在那台机器上,没办法帖过来,反正就是说语法错误,目标不存在,然后要我iptables --help自己好好看。运行mct,把防火墙设置里面设为全部允许,保存,观察了一下,是和iptables有关,正在关闭iptables、应用新规则、启动iptables……
我已经按照提示在 /etc/sysctl.conf 文件里面修改了 net.ipv4.ip_forward = 1 ,可是,重启机器,还是不行,555,谁来帮帮我。
mct修改的iptables的配置文件到底是什么? # Generated by iptables-save v1.2.6a on Tue Oct 29 22:28:14 2002

为什么gugong的帖子里面那些都是ACCEPT? 我这个也是抄的,不清楚怎么写,反正copy过来也可以用 不求甚解的典型啊,呵呵,不好意思,其实我比不求甚解更糟糕。 Accept 和不是都是一样的! 如果是用adsl虚拟拨号上网,若不设网关,则默认为ppp0。
