Port Triggers - Zoom Cable Modem/Router User Manual

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.
To access the Port Triggers page:
1
Click Advanced in the menu bar.
2
Then click the Port Triggers submenu.
Figure 18 shows an example of the menu and Table 13 describes the items you can
select.
