First off we would need to know what is in your /etc/sysconfig/iptables file.
There could be many things that are killing this. Since it looks like you
are doing statefull inspection I would assume that there is a statement for
ESTABLISHED,RELATED in there also. What are the default policies? Are you
logging your firewall drop/rejects? Check message file to see if there are
any clues in there. We need to know how it is setup completely so one
command isn't killing another.

Normally you would want your Deny lines towards the bottom on your chains if
you have any.

Well paste bin your firewall rules and post the URL here. That would be a
Smile... it increases your face value!
