.. note:: **Documentation under development**
********
Overview
********
In this section there's useful information of all firewall configuration that
can be done regarding bridge, and appropiate op-mode commands.
Configuration commands covered in this section:
.. cfgcmd:: set firewall bridge ...
From main structure defined in :doc:`Firewall Overview</configuration/firewall/index>`
in this section you can find detailed information only for the next part
of the general structure:
.. code-block:: none
- set firewall
* bridge
- forward
+ filter
- name
+ custom_name
Traffic which is received by the router on an interface which is member of a
bridge is processed on the **Bridge Layer**. A simplified packet flow diagram
for this layer is shown next:
.. figure:: /_static/images/firewall-bridge-packet-flow.png
For traffic that needs to be forwared internally by the bridge, base chain is
is **forward**, and it's base command for filtering is ``set firewall bridge
forward filter ...``
