Port Triggering
If you configure port triggering for a certain application, you need to identify a so-called
trigger port and the protocol (TCP or UDP) this port uses. You then assign the public
ports that have to be opened for the application to this trigger port.
You can select known Internet services for this or assign ports or blocks of ports manu-
ally.
ì
To set up port triggering for a service, select Port Triggering in the Address Trans-
lation (NAT) menu.
ì
Select the required application from the Predefined applications list.
ì
Select the option in the Enabled column.
ì
Click the Add button. The data for the required service is entered on the screen.
If the application you require is not in the list, you must enter the relevant data on the
screen manually:
ì
Local protocol: Select the protocol that is to be monitored for outgoing traffic.
ì
Local port: Enter the port that is to be monitored for outgoing traffic.
ì
Public protocol: Select the protocol that is to be allowed for incoming data traffic.
ì
Public port: Enter the port that is to be opened for incoming traffic.
ì
Comment: Enter a description to help you identify different entries.
Note:
You can enter a single port number, several individual port numbers separated by
commas, port blocks consisting of two port numbers separated by a dash or any
combination of these, for example 80,90-140,180).
