•
After a PC has finished using a port triggering application, there is a time-out period before the
application can be used by another PC. This is required because the DGFV338 cannot be sure
when the application has terminated.
To add a new port triggering rule:
1.
Select
Security
from the main menu and
Port Triggering
from the submenu. The Port
Triggering screen will display.
2.
Enter a user-defined name for this rule in the
Name
field.
3.
From the
Enable
pull-down menu, indicate if the rule is enabled or disabled.
4.
From the
Protocol
pull-down menu, choose either TCP or UDP transport protocol.
5.
In the
Outgoing (Trigger) Port Range
fields:
a.
Enter the
Start Port
range (1 - 65534).
b.
Enter the
End Port
range (1 - 65534).
6.
In the
Incoming (Response) Port Range
fields:
a.
Enter the
Start Port
range (1 - 65534).
b.
Enter the
End Port
range (1 - 65534).
