iptables disturb DNS? - Linux Setup, Configuration & Administration

Hello! After weeks' frustration, I have worked out the vsftpd problem (Thanks to Vwakes!) by stop iptables. (/etc/init.d/iptables stop under RH8.0). Now I restart the iptables for some obscure fear of less security. But I found I cannot connect to the web sites then! (Mozilla1.4). I stop iptables, and the connections all are OK. Could someone help to explain? The iptables config is the default one on RH8.0. Thanks for your time, Wenjie...

    Default iptables disturb DNS?

    Hello!


    After weeks' frustration, I have worked out the vsftpd problem
    (Thanks to Vwakes!) by stop iptables. (/etc/init.d/iptables stop
    under RH8.0).

    Now I restart the iptables for some obscure fear of less security.
    But I found I cannot connect to the web sites then! (Mozilla1.4).

    I stop iptables, and the connections all are OK.

    Could someone help to explain? The iptables config is the default
    one on RH8.0.


    Thanks for your time,

    I can't believe that this is the RH default. Are you really sure that you
    haven't changed it?
    Maybe you can post your iptables rules (iptables -L).
