[CentOS] fail2ban problem new installation

Hello,

I have a big problem with fail2ban and firewalld on my new system.

I have a server running (CentOS 7.1) and run a Update to 7.2 on this system 
all is working ?

BUT I install a new system with CentOS 7 1511 on this systems fail2ban don't 
work anymore. I have this error  or more, in the firewalld

2015-12-19 08:39:55 ERROR: COMMAND_FAILED: '/sbin/iptables -w2 -t filter -I 
INPUT_direct 1 -p tcp -m multiport --dports ssh -m set --match-set fail2ban-
sshd src -j REJECT --reject-with icmp-port-unreachable' failed: iptables 
v1.4.21: Set fail2ban-sshd doesn't exist.
                                                  
Try `iptables -h' or 'iptables --help' for more information.

Is on 7.2 some missing or not installed

I installed fail2ban from the epel repo.
Thanks for a answer,
