Hello.

Just open up Applications->System Configuration->Security Level and add 
the following in the space where you can write:

123:udp,123:tcp

That will open the ports 123 in TCP and UDP mode... Apply, restart the 
iptables service (system-config-services or Applications->System 
Configuration->Servers->Services) look for the iptables service and 
restart it or issue (as root) /sbin/service iptables restart.
