If you'll not find the documented way how to do it, you can try to use LSP
to check parameters
used in winsock

Seems , like winsock check app send raw socket , in the case it's DHCP
agent, it do allow to send packet for unbound miniport. You can try to
use
TDIMon from sysinternals to check both
cases (http://www.sysinternals.com/Utilities/TdiMon.html)

Thanks a lot for your help Arkady.

This tool TdiMon is great.
I can see that the "DHCP Client" Service (process svchost.exe)
successfully sends a TDI_SEND_DATAGRAM from 0.0.0.0:68 to
255.255.255.255:67 using UDP. But my process trying to do the same
gets a result HOST_UNREACHABLE.

I get this using a classical UDP socket, not a RAW socket. I do not
think I need to use RAW socket in fact. Do you think that the control
you mentioned about the application not only applies to RAW Sockets,
but also to UDP sockets? Have you found this information from
Microsoft, or is it a guess?

best regards

Do you have the value of this option?
Does that mean that if I can not set this option, I won't be able to
broadcast from 0.0.0.0, and there is no solution to my problem?

Thank you very much for your help
