Luis,

If you cannot see port 3050 open via internet maybe you have some
firewall blocking it.
I assume the ADSL modem is connected to the "server" computer (where FB
runs).

Try to telnet port 3050 wih sometinh like

telnet 200.X.Y.Z 3050

If you have some firewall you should get an error, like connect reject
by the server or something similar, if you get connected then port 3050
is open.

See you !
