Message-Id: List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable To: lartc@vger.kernel.org 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 ;-)=20 if the box has the IPs, it kows it and route it internally. _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
