I''m not sure if this is the same thing as what the original poster was
asking,
but I have a similar issue: there are two ethernet interfaces on a box, and
for HW diagnostic purposes I want to send IP traffic _over the wire_ from one to
the other. In the
normal case, this would be handled via the loopback device and would not go over
the wire (since the internal routing code is smart enough, I believe, to check
all
local interface addresses). I expect there is a way to do this with policy
routing,
and I''ll be looking into it,
but if someone already knows some answers, please share them.
Thanks,
sf

Use Linux ;-)=20
if the box has the IPs, it kows it and route it internally.
