Please check that your rules are loaded as desired following the first reboot after configuration.
iptables Service for RedHat Enterprise Linux (RHEL) and CentOS
RHEL/CentOS also offer simple methods to permanently save iptables rules for IPv4 and IPv6.
There is a service called "iptables". This must be enabled.
chkconfig --list | grep iptables
iptables 0:off 1:off 2:on 3:on 4:on 5:on 6:off
chkconfig iptables on
chkconfig ip6tables on
The rules are saved in the file /etc/sysconfig/iptables for IPv4 and in the file /etc/sysconfig/ip6tables for IPv6. You may also use the init script in order to save the current rules.
