5 Only Jane can connect to the Real Audio server until the connection is closed or
times out. The WiMAX Device times out in three minutes with UDP (User
Datagram Protocol), or two hours with TCP/IP (Transfer Control Protocol/Internet
Protocol).

and going to the outside.
2 If an application needs a continuous data stream, that port (range) will be tied up
so that another computer on the LAN can’t trigger it.
