Howto load iptables rules at boot time on Debian 8 Linux system

In this mini post I’ll show you how to save, and load your iptables rules at boot time on Debian 8 “Jessie”, and Ubuntu 14.04, and higher.

To save, and load your current iptables rules at boot, and halt time “make them persistent”, you need to install extra package “iptables-persistent”, run the following command, and accept all OK by pressing ENTER key:

# apt-get -y install iptables-persistent

Now, all your applied iptables rules will be loaded at boot, and halt time.

If you added any rules after installing the above package, run the following command to save it, and load it at boot time.

# netfilter-persistent save
run-parts: executing /usr/share/netfilter-persistent/plugins.d/15-ip4tables save
run-parts: executing /usr/share/netfilter-persistent/plugins.d/25-ip6tables save

Now both your existing, and new rules will be loaded at boot time.
