4.10.2 Port Triggering 
Choose menu “Forwarding”→  Port Triggering”, you can view and add port triggering in the 
next screen (shown in Figure 4-61). Some applications require multiple connections, like Internet 
games, video conferencing, Internet telephoning and so on. Port Triggering is used for some of 
these applications that cannot work with a pure NAT modem router.
