Port Triggering - Siemens Gigaset SE361 WLAN User Manual

Port triggering

If you configure port triggering for a certain application, define a so-called trigger port
and the protocol (TCP or UDP) this port uses. To this trigger port you then assign the pub-
lic 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, select Port Triggering in the Address Trans-
lation (NAT) menu.

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