  i can ftp to yoyo.cc.monash.edu.au for example and get no errors.

  time to email the server hosting my domain.

    Hmm, you get that error when using active mode behind a NAT router (which a 
    Linux box doing IP masq is).  You have two choices:

    1.  Use passive mode on your FTP client.

    2.  Load the ip_masq_ftp module on the IP masq gateway box.  This module 
    fudges the port commands so active FTP works.  If you're FTPing to a non 
    standard port, you may need to specify that port in the options for the 
    module in /etc/modules.conf (read the docs :) ).
