No iptables bootup action was found, indicating that the IPtables package is not installed on your system

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.

I am from a Microsoft Azure background, and now looking for a change in Microsoft Azure Certification Exams. There is no doubt that Now since do not have much knowledge of Microsoft Azure Exams. Will Microsoft Azure Certification help in getting a decent job?
