Port triggering allows devices on the LAN or DMZ to request one or more ports to
be forwarded to them. Port triggering waits for an outbound request from the LAN/
DMZ on one of the defined outgoing ports, and then opens an incoming port for
that specified type of traffic.
Port triggering is a form of dynamic port forwarding while an application is
transmitting data over the opened outgoing or incoming ports. Port triggering
opens an incoming port for a specific type of traffic on a defined outgoing port.
Port triggering is more flexible than static port forwarding (available when
configuring firewall rules) because a rule does not have to reference a specific
LAN IP or IP range. Ports are also not left open when not in use, which provides a
level of security that port forwarding does not offer.
To add a port triggering rule:
Click Networking > Port Triggering. The Port Triggering page opens.
Enter the following information:
•
WAN Port: Select the WAN interface to configure port triggering for.
•
LAN Port: Select the LAN port to configure port triggering for.
•
Protocol: Select either TCP or UDP protocol.
•
Triggering Range: Enter the port number or a range of port numbers that will
trigger this rule when a connection request from outgoing traffic is made. If
the outgoing connection uses only one port, enter the same port number in
both fields.
•
Forwarding Range: Enter the port number or a range of port numbers used
by the remote system to respond to the request that it receives. If the
incoming connection uses only one port, then specify the same port number
in both fields.
•
Status: Check Enable to enable the port triggering rule, or check Disable to
disable this rule.
Click Add to add this port triggering rule in the list.
To edit a port triggering rule, select the corresponding rule and click the Edit icon.
To delete a port triggering rule, select the corresponding rule and click the Delete
