of port numbers used by the remote system to respond to the request it receives.
If the incoming connection uses only one port, then specify the same port number

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.
