Issue Ubuntu 20.04 LTS + Plesk Obsidian Firewall Ext. says: iptables is needed...

[Joachim_Weisse]

Hello,

I installed (Hosted by Hetzner) Ubuntu 20.04 LTS + Plesk Obsidian Web Pro Edition. I installed the Plesk Firewall xetension and open the Plesk Firewal:

Error: The Firewall module requires Iptables to be installed. Please install the Iptables package from your OS vendor.

Then I read, Ubuntu 20.04 prefers nftables and not anymore iptables. Is that right?

At this point I have to ask, what is the prefered way to come up to a runing Plesk Firewall Extension with Ubuntu 20.04 LTS? (fresh server installation)

At the distribution/Plesk paket from Hetzner (Plesk Obsidian+Ubuntu 20.04 LTS) is iptables, nftables or ufw not pre-installed - what I have to install and what way to proper work with Ubuntu 20.04 LTS AND Plesk Obsidian Firewall Extension?

Best regards

You will have to do: apt install netfilter-persistent iptables-persistent

AFAIK the Plesk firewall extension only works with iptables, not with nftables.
