It'll only cause a conflict if you happen to be on the same ethernet segment. MAC addressing is only used on a "local" ethernet network. It doesn't pass routers. Oh, so I suppose you don't want to be on neighboring segments either. That would be a good way to *really* confuse a router--broadcast arp yourself as a MAC addr already on the other side. An intelligent implementation will ignore you. A foolish implementation will break hardcore. I'd lay money that Cisco routers do it right and Intel routers do it wrong. ;^> The chances of running into someone else without doing it on purpose are pretty slim. -- gabriel rosenkoetter gr@eclipsed.net Attachment:
