  Same solution -- inspection of connections to 21 port, without any
 address translation. And if FTP server uses non-standard control
 port, yes, here is a problem, but it cannot be solved with NAT too
 (or your NAT/firewall should expect each and every connection for FTP
 commands, which is heavy and error-prone task).
