I just hooked an old 486 (ex0) and my office machine (fxp1) together to do some firewall and NATD games. I used BNC rather than crossover (I can add machines just by using more wires), but I have the two machines on a their own LAN. It _was_ as easy as the docs say (once I managed to get FreeBSD installed on the 486 with an ol' Sony proprietary CDROM). -- Crist J.
