FTP listens on port 21. When an outside request comes in for
ftp, the ftp daemon and the outside client negotiate a port.
The firewall detects this desire on the part of the ftp server
and opens up the port. When the use of the port is finished,
the port is closed. That is the way that firewalls work.
