Hi everyone. I searched the forums and I see a similar issue but the solution for that one won't work for me.
In my situation I installed VirtualMin via the install.sh on a completely clean and updated installation of CentOS 7 + Perl.
Everything works great and after changing my SSH and FTP ports and installing fail2ban I manually entered my IPTables rules:
iptables:
-F
-A INPUT -p tcp --dport 1964 -j ACCEPT
-A INPUT -p tcp --dport 10000 -j ACCEPT
-A INPUT -p tcp --dport 123 -j ACCEPT
-A INPUT -p udp --dport 123 -j ACCEPT
-A INPUT -p tcp --dport 1965 -j ACCEPT
-P INPUT DROP
-P FORWARD DROP
-P OUTPUT ACCEPT
-A INPUT -i lo -j ACCEPT
-A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
/sbin/service iptables save
iptables -L -v
Chain INPUT (policy DROP 0 packets, 0 bytes)
pkts bytes target prot opt in out source destination
0 0 fail2ban-SSH tcp -- any any anywhere anywhere tcp dpt:ssh
92 7640 ACCEPT tcp -- any any anywhere anywhere tcp dpt:solid-e-engine
0 0 ACCEPT tcp -- any any anywhere anywhere tcp dpt:ndmp
0 0 ACCEPT tcp -- any any anywhere anywhere tcp dpt:ntp
152 11552 ACCEPT udp -- any any anywhere anywhere udp dpt:ntp
0 0 ACCEPT tcp -- any any anywhere anywhere tcp dpt:tivoli-npm
0 0 ACCEPT all -- lo any anywhere anywhere
100 9983 ACCEPT all -- any any anywhere anywhere state RELATED,ESTABLISHED
Chain FORWARD (policy DROP 0 packets, 0 bytes)
pkts bytes target prot opt in out source destination
Chain OUTPUT (policy ACCEPT 214 packets, 26613 bytes)
pkts bytes target prot opt in out source destination
Chain fail2ban-SSH (1 references)
pkts bytes target prot opt in out source destination
0 0 RETURN all -- any any anywhere anywhere
Anyway.... I went in to look at the configuration module and I get the notification that: No iptables bootup action was found, indicating that the IPtables package is not installed on your system
What did I do?!
Did you come right? I want to know if Virtualmin comes pre-configured with firewall rules, but when I go to Webmin I get a similar message...

I run into this problem right now. Although some time went by since the question was raised, I post my solution. First check the status of firewall related services with service status iptables and service status firewalld. I found that a unit iptables does not exist, so I installed iptables-services and iptables-utils - what will install iptables, too, if missing. Afterwards you can use the firewall module of Vrtualmin.
Good luck Hartmut

I had the same problem too.. It is strange. Maybe the install.sh does not really take care of that. I will try your fix and will report.
Howdy,
Note that with CentOS 7, it uses FirewallD rather than iptables for the firewall service. That's a RHEL/CentOS default, not a Virtualmin setting.
If you're looking to change firewall rules on a new CentOS 7 system, you'd want to look in Webmin -> Networking -> FirewallD.
