+UDP Broadcast Relay
+###################
+
+Certain vendors use broadcasts to identify their equipment within one ethernet
+segment. Unfortunately if you split your network with multiple VLANs you loose
+the ability of identifying your equipment.
+
+This is where "UDP broadcast relay" comes into play! It will forward received
+broadcasts to other configured networks.
+
+Every UDP port which will be forward requires one unique ID. Currently we
+support 99 IDs!
+
+Configuration
+-------------
+
+.. cfgcmd:: set service broadcast-relay id <n> description <description>
+
+   A description can be added for each and every unique relay ID. This is
+   useful to distinguish between multiple different ports/appliactions.
+
+.. cfgcmd:: set service broadcast-relay id <n> interface <interface>
+
+   The interface used to receive and relay individual broadcast packets. If you
+   want to receive/relay packets on both `eth1` and `eth2` both interfaces need
+   to be added.
+
+.. cfgcmd:: set service broadcast-relay id <n> port <port>
+
+   The UDP port number used by your apllication. It is mandatory for this kind
+   of operation.
+
+.. cfgcmd:: set service broadcast-relay id <n> disable
+
+   Each broadcast relay instance can be individually disabled without deleting
+   the configured node by using the following command:
+
+.. cfgcmd:: set service broadcast-relay disable
+
+   In addition you can also disable the whole service without the need to remove
+   it from the current configuration.
+
+.. note:: You can run the UDP broadcast relay service on multiple routers
+   connected to a subnet. There is **NO** UDP broadcast relay packet storm!
+
+Example
+-------
+
+To forward all broadcast packets received on `UDP port 1900` on `eth3`, `eth4`
+or `eth5` to all other interfaces in this configuration.
+
+.. code-block:: none
+
+  set service broadcast-relay id 1 description 'SONOS'
+  set service broadcast-relay id 1 interface 'eth3'
+  set service broadcast-relay id 1 interface 'eth4'
+  set service broadcast-relay id 1 interface 'eth5'
+  set service broadcast-relay id 1 port '1900'
