FTP Server help

[Longy]

I've just set up a ftp server for certain customers to send us files on a old Mac OS X box. I've opened all the ports needed including the large range for passive connections but for some reason I can't connect from client side using passive mode on most FTP Clients - it works ok on active connections and it also fine using fetch on a mac as a passive connection:
