Such is the nature of the FTP protocol.

Try "iptables -A INPUT -p tcp -s A.B.C.D/255.255.255.255 --dport
1024:65535 -j ACCEPT"

to the server, while using "active" mode (normally the default) the
FTP server initiates the data connection back to the client (which can
present problems if there is a firewall active).
