Failed to start iptables-persistent.service

Ubuntu 16.04.2

In a book I read that we need iptables-persistent. The book was published in 2016.

Ok:

sudo apt install -y iptables-persistent

Everything installed. No problems so far. If I reboot the computer, iptables is still here.

Then in the book I read:

sudo service iptables-persistent start.

And I get this:

Failed to start iptables-persistent.service: Unit iptables-persistent.service not found.

Could you comment: is it acceptable behavior for Ubuntu 16.04.2?

Solution 1:

It seems since Ubuntu 16.04, iptables-persistent has been replaced by netfilter-persistent. The package still exist and automatically install netfilter-persistent thanks to a dependancy. It's possible to use the following command to start the firewall.

sudo service netfilter-persistent start
