Port Forwarding Setup
Port forwarding enables multiple server applications on a LAN to serve clients on a WAN over a single WAN IP address. The router
accepts incoming client packets, filters them based on the destination WAN, or public, port and protocol and forwards the packets to
the appropriate LAN, or local, port. Unlike the DMZ feature, port forwarding protects LAN devices behind the firewall.
To view the Port Forwardung settings, click
Advanced
then select
Port Forwarding
.
Enable Port Forwarding
Click Enable Port Forwarding to active port forwarding.
Description
Enter notes or details about the forwarded port configuration.
Local IP
Enter the local IP address of the server behind the NAT firewall.
Protocol
Select the protocol to use for mapping from the following: TCP,
UDP or Both.
Local Port
Enter the LAN port number that WAN client packets will be
forward to.
Public Port
Enter the WAN port number that clients will send their packets
to.

Port Triggering Setup
Some applications, such as online games, videoconferencing and VoIP telephony, require multiple ports for inbound and outbound
traffic. If an application requires simultaneous use of incoming and an outgoing ports, configure port triggering to map a local port or
range of ports to a specific public port. Sending packets out over the local port triggers the router to open an incoming local port that
is mapped to the same public port and application as the outgoing local port(s). The local application can communicate over the
incoming and outgoing ports without the need for creating a fixed address.
To view the Port Triggering settings, click
Advanced
then select
Port Triggering
.
Enable Port Triggering
Click Enable Trigger Port to activate port triggering.
Description
Enter notes or details about the port triggered configuration.
