===========================
Floating IP port forwarding
===========================
Floating IP port forwarding enables users to forward traffic from a
TCP/UDP/other protocol port of a floating IP to a TCP/UDP/other protocol port
associated to one of the fixed IPs of a Neutron port. This is accomplished by
associating ``port_forwarding`` sub-resource to a floating IP.
CRUD operations for port forwarding are implemented by a Neutron API extension
and a service plug-in. Please refer to the Neutron API Reference documentation
for details on the CRUD operations.
Configuring floating IP port forwarding
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
To configure floating IP port forwarding, take the following steps:
* Add the ``port_forwarding`` service to the ``service_plugins`` setting in
``/etc/neutron/neutron.conf``. For example:
.. code-block:: console
service_plugins = router,segments,port_forwarding
* Set the ``extensions`` option in the ``[agent]`` section of
``/etc/neutron/l3_agent.ini`` to include ``port_forwarding``. This has to be
done in each network and compute node where the L3 agent is running. For
example:
.. code-block:: console
extensions = port_forwarding
.. note::
The ``router`` service plug-in manages floating IPs and routers. As a
consequence, it has to be configured along with the ``port_forwarding``
service plug-in.
.. note::
After updating the options in the configuration files, the neutron-server
and every neutron-l3-agent need to be restarted for the new values to take
effect.
After configuring floating IP port forwarding, the
``floating-ip-port-forwarding`` extension alias will be included in the output
of the following command:
.. code-block:: console
$ openstack extension list --network
