A few hours of cursing and tweaking and digging around in obscure dialogs got ftp back up and running on the old W2K box on the DSL. Punching the hole in the router was no problem (good tips at http://www.linksysftp.org), nor forwarding to the correct machine. Had Terminal Services running on the server, and finally thought to check ftp properties. Still bound to the old IP address. Doh.
