Port Triggering is a variation of open ports function.
The key difference between "open port" and "port triggering" is:
Once the OK button is clicked and the configuration has taken effect, "open port" keeps

the ports opened forever.
 Once the OK button is clicked and the configuration has taken effect, "port triggering"
will only attempt to open the ports once the triggering conditions are met.
 The duration that these ports are opened depends on the type of protocol used. The
"default" durations are shown below and these duration values can be modified via
telnet commands.
TCP: 86400 sec.
UDP: 180 sec.
IGMP: 10 sec.
TCP WWW: 60 sec.
TCP SYN: 60 sec.
Available settings are explained as follows:
