Configuring the Advanced Settings

Port Triggering

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.

ìTo set up port triggering for a service, in the Address Translation (NAT) menu, select Port Triggering.

ìSelect the required application from the Predefined applications list.

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

ìSelect 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:

ìLocal protocol: Select the protocol that is to be monitored for outgoing traffic.

ìLocal port: Enter the port that is to be monitored for outgoing traffic.

ìPublic protocol: Select the protocol that is to be allowed for incoming data traffic.

ìPublic port: Enter the port that is to be opened for incoming traffic.

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).

ìComment: Enter a description to help you identify different entries.
