How start a script or command during the fedora startup

Question

I try for two or three hours , to exec a command with a script during the boot of fedora 23.

I see some tutorials with chkconfig but on my fedora, i have only systemctl, chkconfig is too old no ?.

I try to create a service but even when i exec : systemctl enable my_service after the reboot , that does not exec my service. manually systemctl start my_service works.

But more weird it's that the service starts because when i write systemctl list-unit-files –type=service , i see my iptablesvpn.service enable . So really i don't understand why the command inside the script is not executed or maybe to soon, i don't know :/

So i trieda other solution which is to add a script in /etc/init.d/script.sh with a chmod +x on it. But even that does not work.

I just want to restore iptables after the reboot. So i want something like: /sbin/iptables-restore /etc/firewall.rules. After the boot, if i write this command in a terminal, that work and my vpn is happy but if don't write this command my vpn does not work.

So if you can help me to exec this command line , i will be happy because that seems to be very simple but it's not for me :/. Thank you

这是我的进程，即使它没有在启动时使用脚本shell进行优化，也可以正常工作：

1） iptables -F
iptables -P INPUT ACCEPT
iptables -F
iptables -A INPUT -i lo -j ACCEPT
iptables -A INPUT -m state -state ESTABLISHED，RELATED -j ACCEPT
iptables -A INPUT -p tcp -dport 22 -j ACCEPT
iptables -P INPUT DROP
iptables -P FORWARD DROP
iptables -P OUTPUT ACCEPT
iptables -L -v

2）编辑/ etc / sysconfig / iptables-config并在Fedora上停止并重新启动关于iptables保存选项的“是”而不是“否”

3）在/etc/rc.d/rc.local中创建一个脚本shell，我写service iptables restart并且它很好:)

你在这个过程中看到一些无用或奇怪的东西？
