That's because of the cloned MAC. The MAC addresses are
used to route the packets at the ethernet (physical) layer
and are expected to be unique (originally they were
supposed to be cast in the hardware and unchangeable)
With the cloned MAC, you have two devices with same MAC...
so the MN-100 gets confused. In other words, it does not
know on which line to send the data to reach a MAC address,
since there are two devices with the same MAC -- probably
the MS programmer set a failsafe mode when that happens and
just broadcasts all the data automatically.
Can you go to the NIC that you cloned and change its MAC
address? Many NICs allow this -- you should be able to get
to this data under Control Panel/System/Devices and look
for the network NIC...
As a side note, DHCP is simply a protocol to assign IP's to
network devices (or computers). It is only run very
sporadically to obtain an IP and renew leases -- DHCP
related logs should appear in the security logs of the
router. The broadcast problem has nothing to do with DHCP.
