There are "managed switches" and "unmanaged switches". You have an unmanaged switch. You might shop for a managed switch. Expect to pay twice as much. Probably more as unmanaged switches have become commodity items. MAC spoofing is as simple as "ifconfig fxp0 lladdr 1;2:3:4:5:6". I do it myself rather than call my ISP and change my registered MAC address. Then again, guess the support line is staffed right now, so maybe I really oughta call. Darn! I forgot what the card's real MAC is. Guess I have to go look and see how to un-lladdr the interface. Maybe I can drop it, then add it, and get the one out of hardware. Heaven forbid that I might have to reboot to get the default... Hey that's it. Its in /var/run/dmesg.boot. Thanks for the help!
