I'm not sure if this is the same thing as what the original poster was aski= ng,=20 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 o= ne to=20 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 ch= eck 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.

Use Linux ;-)=3D20 if the box has the IPs, it kows it and route it internally.
