Lee is almost certainly correct; HylaFAX apes FTP, and FTP, remember,
connects *back* to the workstation.  Make sure your filrewalling drops
turds in the log file, and you should be able to see where you need to
punch a hole.

And note that the implication of "on by default" is that it doesn't
*matter* if *you* enabled the firewall, *RedHat* did it for you.
