Hi, I followed the installation guide for Openstack Juno over Centos7 and I didn't stopped the firewall on the controller and on any other node during the installation I just altered it with each openstack component in order to work properly, for example I used commends like:

# firewall-cmd --add-service=ntp --permanent
# firewall-cmd --reload

in order to allow NTP service to work properly and serve the other nodes, till I reached the installation of Heat at this point I had to stop the firewall completely!! I used this commend systemctl disable firewalld The question is; is there any reference guide or a website that covers all the required firewall changes for each of Openstack components for Juno over Centos7 ? Like what Redhat is doing in there installation guides which clearly states what are the required changes in the iptables https://access.redhat.com/documentati...

Many thanks and if there is question or request does not make sense please advice me to the right direction Thanks again
