What you need it for? You expect dalton's eth1 to be connected with nothing
but carnot by means of a cross-over cable and the bridge will already give
you IP connectivity between them so no need for anything else.
There's in fact no "other interface in the LAN" to interfere with. Or am I
forgetting something?
