555，我的网关还是没搞定！

樱家冢

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？

为什么gugong的帖子里面那些都是ACCEPT[0]？

llc

我这个也是抄的,不清楚怎么写,反正copy过来也可以用

樱家冢

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。

jackey

Accept[0] 和不是[0]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。
