hello, I am new with cpanel, so sorry if its wrong section or whatever, correct me and I ll try to comply, but dont ban or delete for no reason. I have recently setup a centos 6.4 with cPanel latest installer, I did disable SElinux, but not iptables as install instructions advice and to be frank, I cannot risk to open-up all the server public, as it has many crucial data to take my chances... I have left only incoming port 80, 2086 & 2082 to pass and blocked all the rest traffic, in and out (with exception to my preferred centos mirror IP and my IP to manage things), but now, it seems I get a cpanel license error. Is there a specific block of ips / ports I need to allow for cpanel to talk home and fetch license and software updates ? Can cpanel work without problems, if I allow only port 80 & cpanel ports from outside ? thanks for any help !

  Hello :) Ensure TCP outbound traffic is allowed over port 2089 for license verification and let us know if that helps. You can find a list of required ports at: Which ports should be open if my cPanel & WHM server is behind a firewall? Thank you.
