Hi,
FOP2 communicates with web clients on tcp port 4445 by default.
You must port forward port 4445 in your router.
FOP2 uses a synchronous connection to the server to get real time data. It does not poll the server at regular intervals like ajax does. For doing so it uses flash xmlsockets or html5 websockets if the browser supports it.
It users port 80/443 for serving the .js, .html files, but then the communication is done outside http.
Best regards,
