In 4.5, ipchains is no longer used; iptables is used instead.

The changes you make (using the iptables command) are made in the  
kernel's memory.  To save the changes to /etc/sysconfig/iptables, use  
the "service iptables save" command.  When the system is booted (and  
the iptables service is enabled) it will read that file back into the  
kernel's memory.
