What about port 21? and the higher ports 1024 and up? and passive mode settings? are these clients internal and the server external (or vice versa)? If so you must have port 20, 21, and 1024 and up available to start with and then narrow it down from there.

I've checked, and made sure the firewall was allowing port 20, and made sure that port 20 was properly routed. It hasn't helped, though. Wayne S.
