I've just tried it, and it seems to work fine here.
Do you have an user in /etc/passwd called fax_admin?
If not, that's the reason, because faxm uses the uid you are running under
as login name to HylaFAX.

If you think about it you'll find it's useful more than funny :-)
Why to bind to 192 if you can bind to 127 for local submissions?
127.0.0.1 will mean "local connection" for every network config, with or
without network card.

So your internet firewall allows connections originating from private
addresses coming from the public interface? :)
Yes, just block 4559; however, if your fax server has a private ip, it will
be very difficult (impossible unless you explicitly do something) for it to
be reached from the internet.
