N300 Wireless ADSL2+ Modem Router DGN2200v4
Note:
If you use applications such as multiplayer gaming, peer-to-peer
connections, real-time communications such as instant messaging,
or remote assistance (a feature in Windows XP), you should also
enable Universal Plug and Play (UPnP).
To configure port triggering, you need to know which inbound ports the application needs,
and the number of the outbound port that will trigger the opening of the inbound ports. You
can usually determine this information by contacting the publisher of the application or user
groups or news groups.
To enable port triggering:
1.
Select
Advanced > Port Forwarding/Port Triggering
.
2.
Select the
Port Triggering
radio button.
3.
Clear the
Disable Port Triggering
check box.
Note:
If the Disable Port Triggering check box is selected after you
configure port triggering, port triggering is disabled. However, any
port triggering configuration information you added to the modem
router is retained even though it is not used.
4.
In the Port Triggering Timeout field, enter a value up to 9999 minutes.
This value controls the inactivity timer for the designated inbound ports. The inbound
ports close when the inactivity time expires. This is required because the modem router
cannot detect when the application has terminated.
