Port Triggering The Port Triggering feature allows you to forward a range of ports to an IP address on your local network (LAN) only after specific outbound traffic is detected. You can set up a port triggering entry based on your specific ports. IMPORTANT: Using various Internet applications depends on the Router's firewall settings. Make sure that the Router's firewall is set to Medium Security or lower to take advantage of all the port forwarding features. Firewall settings take precedence over port forwarding services configured in the Router. For example, if the firewall is set to Medium Security, this will block ICMP packets even if the ICMP service is enabled. If a port forwarding service is not working, try setting the firewall to a lower setting. Protocol: Displays the protocol/service. Check the box to activate the rule. Outgoing Trigger Ports: Displays the outgoing port(s) and protocol(s) used by the application. Incoming Ports to Displays the incoming port(s) and protocol(s) opened by the application. Open: Action: Click the red X to delete the rule. Add: Select a service/application from the drop-down menu to add. DSL-2750B User Guide 40

Port Triggering
The Port Triggering feature allows you to forward a range of ports to an IP address on your local network (LAN)
only after specific outbound traffic is detected. You can set up a port triggering entry based on your specific
ports.
IMPORTANT: Using various Internet applications depends on the Router’s firewall settings. Make sure that the
Router’s firewall is set to Medium Security or lower to take advantage of all the port forwarding features.
Firewall settings take precedence over port forwarding services configured in the Router. For example, if the
firewall is set to Medium Security, this will block ICMP packets even if the ICMP service is enabled. If a port
forwarding service is not working, try setting the firewall to a lower setting.
