Port forwarding is used to redirect traffic from the Internet from one port on the
WAN to another port on the LAN. Common services are available or you can define
a custom service and associated ports to forward.
The Single Port Forwarding Rules and Port Range Forwarding Rules pages list
all the available port forwarding rules for this device and allow you to configure
port forwarding rules.
Port forwarding is not appropriate for servers on the LAN, since there is a
dependency on the LAN device making an outgoing connection before incoming
ports are opened.
Some applications require that, when external devices connect to them, they
receive data on a specific port or range of ports in order to function properly. The
router must send all incoming data for that application only on the required port or
range of ports.
The gateway has a list of common applications and games with corresponding
outbound and inbound ports to open. You can also specify a port forwarding rule
by defining the type of traffic (TCP or UDP) and the range of incoming and
outgoing ports to open when enabled.

Configuring Single Port Forwarding

To add a single port forwarding rule:
Choose Firewall > Single Port Forwarding. A pre-existing list of applications is
displayed.
In the Application field, enter the name of the application for which to configure
port forwarding.
