ZyWALL times out in three minutes with UDP (User Datagram Protocol) or two hours with TCP/IP

28.5.2 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.
