How to set up port range triggering for

online gaming

For

ALL

Why would I use port triggering instead of port forwarding? Port range

triggering allows the router to watch outgoing data for specific port numbers .

The IP address of the computer that sends the matching data is remembered

by the router, so that when the requested data returns through the router,

the data is routed back to the proper computer . An example of port range

triggering would be to enable a USB or Bluetooth headset for online chat and

gaming .

To set up port range triggering for multiple entries:

Applications & Gaming > Port Range Triggering

1. Log into the browser-based utility (see “How to open the browser-based

utility” on page 25) .

2. Click the Applications & Gaming tab, then click the Port Range

Triggering page .

3. See your device documentation for information on the ports that the

device uses .

4. For each entry in the Port Range Forwarding table:

Enter a descriptive name (such as PS3 Headset)

For single ports, enter the same port number in each Triggered Range

and Forwarded Range box .

For port ranges, enter the same number ranges in each Triggered

Range and Forwarded Range column .

5. Click Save Settings at the bottom of the page .
