If you have setup 'sudo',
$ sudo /sbin/chkconfig iptables off
$ sudo /sbin/service iptables stop

If you haven't setup 'sudo',
$ su -
(type your root password)
# chkconfig iptables off
# service iptables stop

UPDATE: if you prefer gui tool:
1) Go to Main > System Settings > Security Level
2) Type root password
3) Choose Security Level > 'Disable firewall'
