You could catch that with a sanity check inside mpd (don't accept the servers physical address for your own use during negotiation). I've not done this, we simply returned the Cisco box :-) Lars -- Lars Eggert Information Sciences Institute http://www.isi.edu/larse/ University of Southern California To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
