IPTABLES Gone Crazy
The funniest thing is that everytime IPTABLES restarted, it would give the same error again. The domains there will not resolve. It seems that even after trying to add a rule to IPTABLES for PORT 53 to be unblocked, it would still do the same thing.
Does anyone actually know or have encountered this problem before? My client is using CentOS and DirectAdmin. I've asked DA about this problem and they just told me to stop the IPTABLES which I do not think is a good solution.
If anyone could help, it would be very much appreciated. I have found no errors on IPTABLES, the config and etc are all the DEFAULT settings and has not been changed. Plus, APF rules did state that port 53 be opened already.
Please do help out if you have encountered this problem before. Thanks a lot!

OK, if theis machine is on the internal network then you can stop IPTABLES as it should not really be needed. If the External WAN is connecting to this maching then IPTABLES should still be used.
If you want to stop IPTABLES and ensure they are not started again automaicly then do the following:
service iptables stop chkconfig --level 2345 iptables off
