Firewalld Rich Rules basics

This tutorial will help you to get started with the firewalld configuration. Basics on zones and rich rules are presented.

What we do

The shell provisioner will ensure that on all hosts firewalld and curl are installed. For “host_protected” the provisioner will install nginx for demo purposes, too. Furthermore, the firewall will configured on “host_protected”.

Every host has two interfaces NAT (enp0s3) and host-only (enp0s8). The provisioner will not touch the NAT interface (zone: public) rules! Only the host-only interface (zone: home) rules will modified!
