9.3.4 Port Trigger
Trigger port forwarding allows computers on the LAN to dynamically take turns using the service. The
NR2301 records the IP address of a LAN computer that sends traffic to the WAN to request a service with
a specific port number (a “trigger” port). When the NR2301's WAN port receives a response with a
specific port number, the NR2301 forwards the traffic to the LAN IP address of the computer that sent the
request. After that computer’s connection for that service closes, another computer on the LAN can use
the service in the same manner. This way you do not need to configure a new IP address each time you
want a different LAN computer to use the application. See Section 9.16.3 on page 99 for more
information.
To change your NR2301’s trigger port settings, click APP MODULE > Firewall > Port Trigger. The screen
appears as shown.
Note: Only one LAN computer can use a trigger port (range) at a time.
