OREIGNDEVICE
The foreign device settings are located under this submenu. The foreign device feature is used
when the device is located in a different network than the BBMD. A normal router does not send
broadcast messages between different networks. The 'Foreign device' feature solves this
problem by establishing a connection to the BBMD with unicast messages. All broadcast mes-
sages are forwarded to a BBMD device that takes care of receiving and transmitting broadcast
messages in both directions for all foreign devices.
