CentOS - May 2016 - iptables.service listed as: not-found inactive dead

Hello fellow CentOS users,

on a freshly installed 7.2 machine and after reading

https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/System_Administrators_Guide/chap-Managing_Services_with_systemd.html

I try to enable iptables with following commands:

# cat /etc/centos-release
CentOS Linux release 7.2.1511 (Core)

# rpm -qa | grep iptables
iptables-1.4.21-16.el7.x86_64

# sudo systemctl list-units --type service --all | grep iptables
? iptables.service                       not-found inactive dead
 iptables.service

# sudo systemctl enable iptables.service
Failed to execute operation: No such file or directory

What missing file is meant here please?

Thank you
Alex

By default, Centos 7 uses firewalld.

?you need iptables-services rpm (and disable/remove firewalld)?

Thank you, I have put my firewall rules into /etc/sysconfig/iptables:

*filter
:INPUT DROP [0:0]
:FORWARD DROP [0:0]
:OUTPUT ACCEPT [294:35064]
-A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT
-A INPUT -i lo -j ACCEPT
-A INPUT -p icmp -m icmp --icmp-type any -j ACCEPT
-A INPUT -p tcp -m state --state NEW -m tcp -m multiport --dports
25,80,443,8080 -j ACCEPT
-A INPUT -p tcp -m state --state NEW -m tcp --dport 22 --tcp-flags
FIN,SYN,RST,ACK SYN -m limit --limit 2/min --limit-burst 1 -j ACCEPT
COMMIT
Then issued the commands (there was no firewalld installed):

    # yum install iptables-services
    # systemctl enable iptables
    # systemctl start iptables

And it seems to work well now

Regards
Alex
