RHEL, CentOS and SUSE distributions enable a restrictive :term:`firewall` by
|
|
default. During the installation process, certain steps will fail
|
|
unless you alter or disable the firewall. For more information
|

about securing your environment, refer to the `OpenStack Security

|
Guide <https://docs.openstack.org/security-guide/>`_.
