Thanks for reply. It is not multicast, not always anyway.
Will BPF (Berkley Packet Filter) write of the raw packets bypass OSX
routing?
Is there any better solution?
I definitely have to bypass routing, since each interface will be
sending to the
same destination (IP) address.
Thanks,

If you're using multicast packets, you can specify the interface
using a multicast specific option. Otherwise, there is no way to
control which interface the packets are sent on. That decision will
be made based on the routing table.

So far, it seems that MacOSX is always determenes what interface
to use based on destination (sendto) address only.
In Window, it is enough to “bind” socket to specific IP/interface
instead of ANY_ADDR, Linux has SO_BINDTODEVICE
(
see explanation at the http://zuul.slackware.biz/versions/
slackware-3.9/docs/linux-2.0.37pre10/networking/so_bindtodevice.txt
)
Any advise on how to archive it on Mac OSX ?
Thanks,
