for my demo, I did the following:
iptables -F ; chkconfig --del iptables ; ip6tables -F ; chkconfig
--del
ip6tables
This helped (maybe not recommended for production :-))...

don't think clustering is working as expected in your case, cos
without locking this port and opening it in the firewall, you'll see
WARN messages like this in the logs and the cluster view will not
form:
