Hello. I am a newbie with control panels and linux servers in general. I have installed webmin/virtualmin on a clear VPS with Centos 7. The installation was fine. I have seen that this sofware is a bit complicated with many options, however all works very well. I am happy. I have installed a joomla website for testing purposes without problem.
The first thing that claim my attention is the ram consume: it is ok?: Dashborad > Real memory: 837.80 MB used / 3.52 GB total Almost a giga, it's not much? it is right?
Secondly, I have observed that php version installed with Webmin is PHP 7.0. I go to: Webmin > System > Software Packege updates > Only News > And here I found many packeges of PHP 7.1. Which one should I install? Where is PHP 7.2.8? What other ways are there to update this?
Thirdly, In Webmin > Networking, I dont understad how to secure my server. In Linux Firewall I got this error message: "No iptables(6) bootup action was found, indicating that the IPtables package is not installed on your system" However, IPtables is active and running on my server. In FirewallD section, webmin display for me a table with these parameters, but I do not Know if all is ok, or I should to do anything: (note: I have no idea about firewallD and Iptables setup. Both are running on my Centos 7. I think only one is necesary, not both at once)

Sorry, for my newbie questions. Soon I will have many more. Thank you
