求助：WINBOX里PING任何IP都提示 packet rejected

liliangzhi

清除了之前的防火墙
新加入了一个新的防火墙～～
然后PING 客户机的话就提示 packet rejected 了！
是不是禁止PING外网的缘故?我应该修改哪里
PS:我的交换可能是三层的（光钎--3COM交换-ros-华为交换）
防火墙FW表如下：

#使用方法：将此文本文件扩展名改为 .rsc
#登录你的ＲＯＳ的ＦＴＰ，上传此文件
#在控制台（可用winbox 里的New Terminal）执行命令：
# /import fw.rsc

#注意这里的设置中假定你的外网网卡的名字是 外网卡
#需要视情况修改（查找 / 替换）。

#关于ＴＣＰ连接的一些设置，主要是减少连接的存活时间

routerbbs.com的人气好差。。
在那里问了一个星期。。。一个人也没鸟我！

最后管理员admin 叫我禁止ICMP那一段。。但还是不可以。

我一部分一部分的排除把。。也看不出点什么眉目~~~

望高手多指教！！！

漫天

你都明要禁ICMP了。还PING什么？真是的。。要PING就删了ICMP的哪段，不要PING的就别理，能上网就是了
