rightly said,

1)  check wether it is enabled for run level in which you are running 
your server.   
     "chkconfig --level 35 iptables"  OR for temp solution do "service 
iptables start/restart"
2) could check the status
     "service iptables status"
3) save your settings as
     iptables-save > your_iptable_rules
4) check wether " /etc/sysconfig/iptables" exists, if yes make a backup 
of it.
      now put your rules as "iptables-restore < your_iptable_rules"
     can also use "service iptables save"
at last i would suggest you to see "/etc/init.d/iptables" script.

hope this will help a bit.
