Logout SBG6900-AC Advanced - Port Triggers Home > Advanced > Port Triggers The SBG6900-AC can be given triggers that will automatically open a port (or range of ports) for incoming traffic after a port (or range of ports) has been accessed by outgoing traffic. How Port Triggering Works Ports are virtual pathways numbered between 0 and 65535 that the SBG6900-AC and other devices use to sort incoming and outgoing network traffic. Pairs of port triggers and port targets can be configured to automatically route requests. After port triggers have been configured, when a request is sent to the Internet through a trigger port (or port range), the trigger is tripped and a target port (or port range) opens. The now-open target port is ready to receive a request from the Internet. When a request comes to the target port, the request is then routed to the device that tripped the trigger port's trigger. Port Triggers, Part 1: Outgoing Request Request Request Request 21 Target Port or Port Range 22 Trigger Port or Port Range When the Trigger Port (22) is triggered by an outgoing request from a device, the Target Port (21) opens. Port Triggers, Part 2: Incoming Request Request Request Request 21 Target Port or Port Range When the now-open Target Port (21) receives a Request, the Request is routed to the device that tripped the Trigger Port. Configure a Port Trigger/Target for One Port You may want to use a port trigger/target pair to automatically forward requests through one port. To do this, you could create a port trigger with an identical Trigger Start Port and Trigger End Port, like 21, then an identical Target Start Port and Target End Port, like 22, and then selecting UDP, TCP, or Both for the affected protocol. You could then enable the filter by checking the Enabled box and pressing Apply. Later, when a request is sent out through the trigger port, the trigger will be tripped and the target port will be opened. Configure a Port Trigger/Target Pair for a Range of Ports You may want to use a port trigger/target pair to automatically forward requests through a range of ports. To do this, you could create a port trigger with a Trigger Start Port at the beginning of the range (18) and a Trigger End Port at the end of the range (25). You could also create a Target Start Port at the beginning of the range (49) and a Target End Port at the end of the range (55). You could then select UDP, TCP, or Both for the affected protocol and enable the filter by checking the Enabled box and pressing Apply. Later, when a request is sent out through the trigger port range 18 - 25 (inclusive), the trigger will be tripped and the target port range 49 - 55 (inclusive) will be opened. Port Triggering Trigger Range Target Range --> Protocol Each communications protocol uses one of two fundamental protocols to transmit its data on the Internet: User Datagram Protocol (UDP) or Transmission Control Protocol (TCP). Typically, only one or the other is used for any given communications protocol, but sometimes the other is used for special applications --> Description --> Enable Enables the range of ports to be triggered. If this is not enabled, the ports are not triggered -->   --> Start Port The starting port in the range that will trigger a port association --> --> End Port The ending port in the range that will trigger a port association --> --> Start Port The starting port in the range of the target port association --> --> End Port The ending port in the range of the target port association -->   ©2015 ARRIS Group, Inc.
