"service iptables save" will merely copy what you have running
(basically what "iptables -nvL" outputs) and save it to
/etc/sysconfig/iptables, so that that same configuration will be used
on your next reboot (or next time you run "service iptables start" or
"service iptables restart").

Looking at http://pastebin.centos.org/23912 the rule you mentioned is
not there either. Maybe the rule was not loaded when you ran "service
iptables save".

I suggest you verify the output of "iptables -nvL" after you load the
rule again, and verify the contents of /etc/sysconfig/iptables after
you run "service iptables save" again. If there is indeed a problem,
looking at those might give you a clue of where/when it is happening.

HTH,
Filipe
