# OpenStack firewall setup for baserock.org
#
# This rather ugly and verbose Ansible script defines the firewall
# configuration for the baserock.org cloud.
#
# OpenStack security group rules are all ACCEPT rules, and an instance
# can be in multiple security groups.
#
# Note that many systems don't have a floating IP assigned and thus are
# isolated from the internet. Requests to them are proxied by the
# frontend-haproxy system.
#
# This playbook requires the 'neutron_sec_group' module, available in
# <https://github.com/openstack-ansible/openstack-ansible-modules/>.
