If you configure Port Triggering for a certain application, determine a so-called trigger 
port and the protocol (TCP or UDP) this port uses. Then you assign to this trigger port 
the public ports that have to be opened for the application. 
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, in the Address Translation (NAT) menu, 
select Port Triggering.

ì

Select the required application from the Predefined applications list.

ì

Click the Add button. The data for the required service is entered on the screen.

ì

Select the option in the Enabled column.

If the application you require is not in the list, then 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, e.g. 80,90-140,180).
