You can’t bind on port 80, AAF applications are run with specific user rights that don"t allow to access system resources ( TCP ports <1024 are system resources).
What you could try: use Ace Manager port forwarding functionality to try to link port 80 with another port >=1024, and then bind your AAF app on that port (I am not sure it will be allowed.)
Finally you need to know is that the device won’t accept connection coming from the cellular network on that port.
Also, you can’t access to the http module used by Ace Manager. However you can use the http module provided in AAF ( accessed by socket.http, client only unfortunately).
Maybe you could explain a little bit more what you want to do to see if we can find a workaround for that.
