ZyWALL 2 and ZyWALL 2WE

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

12.6.2 Two Points To Remember About Trigger Ports

1.Trigger events only happen on data that is going coming from inside the ZyWALL 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.

Only one LAN computer can use a trigger port (range) at a time.
