Asking "what is the the port range" is not really an answerable 
question.  You are repeating the same question without absorbing the 
answers people are giving you.  Hylafax protocol, like ftp, uses TWO 
ports.  The first one by default is 4559 and, is only "handshaking" as 
you put it.  The second one is different every time and is taken from 
the full range of allowed ports (1024 to 64k).

It seems you keep asking this so you can set up some simple port 
forwarding through your firewall, but as several people have told you, 
that won't work because this second port number is different every time.

Evidently.

If you won't follow the other posters' advice about setting up a 
separate linux box as a router, I suggest you go back to the setup which 
you said worked (put the hylafax server directly on the external IP) and 
buy a second network card for it to pass other traffic on to the rest of 
your LAN.  Of course you'll have to lock it down well, but, as my math 
teacher used to say, "if you can't solve a problem, try a simpler problem".
