Yes, I'm wondering about the "almost always" case. Since machine1 has=20 multiple physical and vlan interfaces, shouldn't a (for example) server=20 bound to one of the existing physical interfaces be able to communicate=20 with machine2, provided that both machines know how to route packets to=20 each other over the vlan interface without IP address? --------------enig6AA979154D3FFBF7E712CC2E Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.5 (GNU/Linux) Comment: Using GnuPG with SUSE - http://enigmail.mozdev.org iD8DBQFGcnAsldnAQVacBcgRAh9CAJ9XOBdL3PgakvwQHIUt8yW5UdkaOwCg+jg9 dOI5mLS5KWYcHumovjfwNoM= =tRUm -----END PGP SIGNATURE----- --------------enig6AA979154D3FFBF7E712CC2E--
