Hi,

HylaFAX uses an extended FTP Protokoll. Port 4559 is used for the=20
Control connection. For the data-connection a random port above
1024 is choosen.

HylaFAX itselve accepts also passive ftp connections but i don't
know which clients can deal with passive connections. WHFC=20
can't be used with passive ftp connections, but it's on my
(virtual) to-do list.
