cisco 515e 防火墙问题请教！！！

feng4321

问题现象：

10网段机器访问dmz影射出去的10.68.32.47地址。经常出现中断，如打开的网页，过一段时间不操作，有时几分钟或更长时间。再次打开此页面时则打不开。此时ping 10.68.32.47 则发现是中断的，等待一段时间后自己就连上了。此情况在第一次访问47网页时也有时存在。

请教会是什么原因呢？
谢谢！
等待中。。。。。。


防火墙配置如下：

我这边连接连接防火墙外网口线的交换机是千兆的，而防火墙外网口是百兆的，由影响么？
谢谢！

1、光电转换器是否工作正常，长PING，看丢包率。

2、网络内部是否存在地址冲突。

3、网络内部是否存在ARP病毒。

你试下不用47地址进行映射，分配该网段的其他地址看看结果如何。
另外，你的配置里存在错误的地方，建议仔细分析配置。

看双工是否匹配
