HylaFAX supports both active and passive mode.  Many FTP clients
automatically fall back to passive mode if they can't establish active
mode connections; some "hardware" firewalls are intelligent enough to
monitor port 21 and figure out what other ports to open/forward.

Whatever it is, clearly either it or you is doing something different with
port 21 and port 4559 traffic, or the associated data ports.
