## Port Triggering

  Port Triggering allows you to do port forwarding without setting a fixed PC. By setting Port Triggering rules, you can allow inbound traffic to arrive at a specific LAN host, using ports different than those used for the outbound traffic. This is called port triggering since the outbound traffic triggers to which ports inbound traffic is directed.
  If you want to forward ports to a PC with a static IP address, see Port Forwarding or Port Range Forwarding.
  To add a new Port Triggering rule, click Add and fill in the fields below. To remove the last rule, click Delete.
Application
  Enter the name of the application in the field provided.
Triggered Range
  Enter the number of the first and the last port of the range, which should be triggered. If a PC sends outbound traffic from those ports, incoming traffic on the Forwarded Range will be forwarded to that PC.
Forwarded Range
  Enter the number of the first and the last port of the range, which should be forwareded from the Internet to the PC, which has triggered the Triggered Range.
Enable
  Click the Enable checkbox to enable port triggering for the application.
  Check all values and click Save Settings to save your settings. Click the Cancel Changes button to cancel your unsaved changes.

  #### Note
