N300 Wireless Dual Band ADSL2+ Modem Router DGND3300v2 User Manual 7. Click Apply. The service appears in the list. Port Triggering Port triggering is an advanced feature that can be used to easily enable gaming and other Internet applications that would otherwise be blocked by the firewall. Using this feature requires that you know the port numbers that are used by the application. Note: For information about port forwarding and port blocking, see Firewall Rules on page 38. Once configured, port triggering operates as follows: 1. A PC makes an outgoing connection using a port number defined in the Port Triggering table. 2. The N300 wireless modem router records this connection, opens the incoming port or ports associated with this entry in the Port Triggering List, and associates them with the PC. 3. The remote system receives the PC's request, and responds using a different port number. 4. The N300 wireless modem router matches the response to the previous request, and forwards the response to the PC. (Without port triggering, this response would be treated as a new connection request rather than a response. As such, it would be handled in accordance with the port forwarding rules.) Note: Only one PC can use a port triggering application at any time. After a PC has finished using a port triggering application, there is a short time-out period before the application can be used by another PC. To configure port triggering: 1. In the main menu, select Security > Port Triggering. The Port Triggering screen displays. Chapter 3. Security Settings | 43
