Enter the IP address to which forwarded traffic should be sent.

public internet; doing so will grant access to those devices only. If
you enter no External device Addresses, any device on the public
Internet may access your devices.

Description
Enter the Description name here.
Enable
Select ON or OFF to enable Port Forwarding rule.
Note: You may need to assign static IP addresses to devices on your LAN to insure that
the port forwarding you have set up will always apply to them.
Port Triggers
The Port Triggers page allows you to configure dynamic triggers to specific devices on
the LAN. This allows for special applications that require specific port numbers with
bi-directional traffic to function properly. Applications such as video conferencing, voice,
gaming, and some messaging program features may require these special settings.
Port Triggers are similar to Port Forwarding except that they are not static ports held
open all the time. With the port triggering function, the Cable Modem/Router detects
outgoing data on a specific IP port number and opens corresponding target ports for
incoming data. If no outgoing traffic is detected on the Trigger Range ports for 10
minutes, the Target Range ports will close.
