请教:vmware + rhel5 无法上网,ping/nslookup正常!

烧鸡翼

vmware5 采用 bridged 方式
host OS windowsXP_sp2 ip:192.168.0.83 可以正常上网
client OS rhel5 ip:192.168.0.110 无法上网
gateway:192.168.0.1
在rhel5中打开firefox,在建立连接时,先显示正在解释主机 www.163.cm ...
然后显示正在连接到 www.163.com ...
最后显示 位于某某的服务器响应时间过长...
连LinuxQQ也上不了,郁闷...
请教是哪里设置不当造成的?
以下是rhel5的网络设置和相关测试:

烧鸡翼

补充一下:在XP和rhel之间ftp什么的都正常的

问题是我的域名解释没有问题的呀,不明白为什么上不了网,
今天试了一下,从rhel往外ftp,Telnet均告失败,但从外面ftp进来可以,
而且这种情况以前是没有的,不知从什么时候开始就上不了网了

烧鸡翼

嗯,今天把瑞星的两个服务停了,发现一切正常了,
最后开启瑞星,新增一条ip过滤规则,问题解决...{:2_165:}

我还以为楼主是在Firefox上面加了代理了呢
