STEP 6 In the Outgoing (Trigger) Port Range section, specify the port number or range of
port numbers that will trigger this rule when a connection request from outgoing

of port numbers used by the remote system to respond to the request it receives.

Configuring Port Forwarding
Port forwarding is used to redirect traffic from the Internet from one port on the
WAN to another port on the LAN. The port forwarding rules menu allows selection
of a service. Common services are available or you can define a custom service
and associated ports to forward.
The Port Forwarding Rule Table lists all the available port forwarding rules for this
device and allows you to configure port forwarding rules. The table contains the
following information:
• Action—Whether to block or allow traffic (always or by schedule) that
meets these filter rules, and when the rule is applicable.
• Service—Service for which this port forwarding rule is applicable.
• Status—A port forwarding rule can be disabled if not in use and enabled
when needed. The port forwarding rule is disabled if the status is disabled
and it is enabled if the status is enabled. Disabling a port forwarding rule
does not delete the configuration.
