| 1. A system for bridging subnet broadcasts across subnet boundaries, comprising:
a receiver configured to receive a first broadcast message, the first broadcast message originating in a first subnet and
being marked to indicate that it originated in the first subnet to prevent rebroadcast of the first broadcast message on the
first subnet;
a repeater configured to send the first broadcast message to a second subnet; and
a replicator configured to broadcast a second broadcast message on the first subnet, the second broadcast message originating
from a subnet other than the first subnet, at least one of the broadcast messages being a UDP broadcast message.
