Firewall-as-a-Service (FWaaS) v1 scenario
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
Enable FWaaS v1
|
||||
---------------
|
||||
|
||||
FWaaS management options are also available in the Dashboard.
|
||||
|
||||
#. Enable the FWaaS plug-in in the ``/etc/neutron/neutron.conf`` file:
|
||||
|
||||
.. code-block:: ini
|
||||
|
||||
service_plugins = firewall
|
||||
|
||||
[service_providers]
|
||||
# ...
|
||||
service_provider = FIREWALL:Iptables:neutron.agent.linux.iptables_firewall.OVSHybridIptablesFirewallDriver:default
|
||||
|
||||
[fwaas]
|
||||
driver = iptables
|
||||
enabled = True
|
||||
|
||||
.. note::
|
||||
|
||||
On Ubuntu, modify the ``[fwaas]`` section in the
|
||||
``/etc/neutron/fwaas_driver.ini`` file instead of
|
||||
``/etc/neutron/neutron.conf``.
|
||||
|
||||
#. Configure the FWaaS plugin for the L3 agent.
|
||||
|
||||
In the ``AGENT`` section of ``l3_agent.ini``, make sure the FWaaS extension
|
||||
is loaded:
|
||||
|
||||
.. code-block:: ini
|
||||
|
||||
[AGENT]
|
||||
extensions = fwaas
|
||||
|
||||
Edit the FWaaS section in the ``/etc/neutron/neutron.conf`` file to indicate
|
||||
the agent version and driver:
|
||||
|
||||
.. code-block:: ini
|
||||
|
||||
[fwaas]
|
||||
agent_version = v1
|
||||
driver = iptables
|
||||
enabled = True
|
||||
conntrack_driver = conntrack
|
||||
|
||||
#. Create the required tables in the database:
|
||||
|
||||
.. code-block:: console
|
||||
|
||||
# neutron-db-manage --subproject neutron-fwaas upgrade head
|
||||
|
||||
#. Restart the ``neutron-l3-agent`` and ``neutron-server`` services
|
||||
to apply the settings.
|
||||
|
||||
Configure Firewall-as-a-Service v1
|
||||
----------------------------------
|
||||
|
||||
Create the firewall rules and create a policy that contains them.
|
||||
Then, create a firewall that applies the policy.
|
||||
|
||||
#. Create a firewall rule:
|
||||
|
||||
.. code-block:: console
|
||||
|
||||
$ neutron firewall-rule-create --protocol {tcp,udp,icmp,any} \
|
||||
--source-ip-address SOURCE_IP_ADDRESS \
|
||||
--destination-ip-address DESTINATION_IP_ADDRESS \
|
||||
--source-port SOURCE_PORT_RANGE --destination-port DEST_PORT_RANGE \
|
||||
--action {allow,deny,reject}
|
||||
|
||||
The Networking client requires a protocol value. If the rule is protocol
|
||||
agnostic, you can use the ``any`` value.
|
||||
|
||||
.. note::
|
||||
|
||||
When the source or destination IP address are not of the same IP
|
||||
version (for example, IPv6), the command returns an error.
|
||||
|
||||
#. Create a firewall policy:
|
||||
|
||||
.. code-block:: console
|
||||
|
||||
$ neutron firewall-policy-create --firewall-rules \
|
||||
"FIREWALL_RULE_IDS_OR_NAMES" myfirewallpolicy
|
||||
|
||||
Separate firewall rule IDs or names with spaces. The order in which you
|
||||
specify the rules is important.
|
||||
|
||||
You can create a firewall policy without any rules and add rules later,
|
||||
as follows:
|
||||
|
||||
* To add multiple rules, use the update operation.
|
||||
|
||||
* To add a single rule, use the insert-rule operation.
|
||||

||||

|
||||
<https://docs.openstack.org/cli-reference/neutron.html>`_
|
||||
in the OpenStack Command-Line Interface Reference.
|
||||
|
||||
.. note::
|
||||
|
||||
FWaaS always adds a default ``deny all`` rule at the lowest precedence
|
||||
of each policy. Consequently, a firewall policy with no rules blocks
|
||||
all traffic by default.
|
||||
|
||||
#. Create a firewall:
|
||||
|
||||
.. code-block:: console
|
||||
|
||||
$ neutron firewall-create FIREWALL_POLICY_UUID
|
||||
|
||||
.. note::
|
||||
|
||||
The firewall remains in PENDING\_CREATE state until you create a
|
||||
Networking router and attach an interface to it.
