This might be a firewall issue.  Putting the FTP server into passive
mode may do the trick.  Originally FTP servers connected back to the
client to send data.  Passive mode has the server wait for the client to
make the data connection.  Typically a client's firewall will allow the
client to connect to the ftp server but block connections originating
from the ftp server.
