| 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 ...``
