Multiple MAC addresses on a single NIC card

NTDEV
1

I am writing some IP telephony test software on Windows 2000 and need
configure a single NIC with multiple MAC addresses. The reason for this is
that each IP phone registers itself with its MAC address and I need to
simulate multiple IP phones using a single PC. Associating multiple IP
addresses to a single adaptor is easy but is there a way to associate
multiple MAC address without writing my own driver? Any suggestions would
be welcome, thanks.

For receives you can use promiscuous mode, but for sends you have to
write an NDIS driver. You could probably write a protocol, IM, or
miniport driver, with the latter being hardware-dependant and therefore
probably not a good idea.

It is impossible without writing a MUX driver with several virtual miniports
from the upper edge.

You may be able to install multiple instances of the
