Configuring the Advanced Settings

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.

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

ìSelect the required application from the Predefined applications list.

ìSelect the option in the Enabled column.

ìClick 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:

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, for example 80,90-140,180).

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