How to Configure Port Triggering on a NETGEAR Router
Port Triggering is an advanced feature that can be used for gaming and other Internet applications.
It is essentially a port forwarding rule (inbound firewall rule) that is not constantly active, but only becomes active when it is "triggered" by detecting certain specified outbound packets.
Once triggered, specified inbound packets (from the Internet) are forwarded to the computer that triggered it.
The following points summarize the differences between port forwarding and port triggering:
- Port triggering can be used by any computer on your network, although only one computer can use it at a time.
- Port forwarding is configured for a single computer on your network.
- Port triggering does not require that you know the computer’s IP address in advance. The IP address is captured automatically.
- Port forwarding requires that you specify the computer’s IP address during configuration, and the IP address can never change.
- Port triggering requires specific outbound traffic to open the inbound ports, and the triggered ports are closed after a period of no activity.
- Port forwarding is always active and does not need to be triggered.
Configuring Port Triggering
- Open a browser and type in the following URL: http://www.routerlogin.com or http://192.168.1.1 or http://192.168.0.1 (depending on the model number of the router)
- Type the user name admin and the password as password and click OK.
- In the Service Name field, type any unique name, for example: Mail, VPN.
- In the Service User drop-down list, select Any (if all computers in the network are to be able to use
- the port triggered service) or, to allow only one computer in the a network, specify the IP address of that computer.
- Select the Service Type, and specify the Trigger Port of the outbound packets that will activate the port triggered service. Example: TCP, 25
- Select the Connection Type of the inbound packets, Example: TCP.
- Fill in the Starting Port and Ending Port fields with the range of the destination ports of the inbound packets that are to be forwarded. If only one port is required, enter the same value in both fields. Example: 113.
