module: vmware_host_firewall_facts
short_description: Gathers facts about an ESXi host's firewall configuration information
description:
- This module can be used to gather facts about an ESXi host's firewall configuration information when ESXi hostname or Cluster name is given.
version_added: '2.5'
author:
- Abhijeet Kasurde (@Akasurde)
notes:
- Tested on vSphere 6.5
requirements:
- python >= 2.6
- PyVmomi
options:
  cluster_name:
    description:
    - Name of the cluster from which the ESXi host belong to.
    - If C(esxi_hostname) is not given, this parameter is required.
  esxi_hostname:
    description:
    - ESXi hostname to gather facts from.
    - If C(cluster_name) is not given, this parameter is required.
