Do you have a firewall blocking arbitrary ports higher up?
ftp doesn't generally use 21 to move the data, only as a control port to
sync the connection etc. All the data transfer happens either on an
arbitrary port, or over raw tcp (I forget which).

If you're behind a masquaraded connection, try loading the module
ftp_conntrack, it might help.
