Ansible firewalld is used to manage firewall rules on host machines. 
This works just as Linux firewalld daemon for allowing/blocking services 
from the port. 
It is split into two major concepts
•	Zones: This is the location for which we can control 
which services are exposed to 
or a location to which one the local network interface is connected.
•	Services: These are typically a series of port/protocol 
combinations (sockets) that your host may be listening on, 
which can then be placed in one or more zones
Few examples of setting up firewalld are
1- name: permit traffic in default zone for https service
2 ansible.posix.firewalld:
3   service: https
4   permanent: yes
5   state: enabled
6   
7- name: do not permit traffic in default zone on port 8081/tcp
8 ansible.posix.firewalld:
9   port: 8081/tcp
10   permanent: yes
11   state: disabled
