Bert,
FTP server's port 21 from anywhere (Client initiates connection)
FTP server's port 21 to ports > 1024 (Server responds to client's control
port)
FTP server's ports > 1024 from anywhere (Client initiates data connection to
random port specified by server)
FTP server's ports > 1024 to remote ports > 1024 (Server sends ACKs (and
data) to client's data port)
