The Ethernet Broadcast Filtering menu enables defining the layer 2 (Ethernet)

customer's LAN but are not relevant for other customers, such as NetBios, which
is used by the Microsoft Network Neighborhood. Enabling this feature blocks
Ethernet broadcasts and multicasts by setting the I/G bit at the destination
address to 1. This feature should not be enabled when there is a router behind
the SU.
