Port Forwarding - D-Link DSL-3580L Series User Manual

Section 3 - Configuration

PORT FORWARDING

Use the PORT FORWARDING window to open ports in your router and re-direct data through those ports to a single PC on your network
(WAN-to-LAN traffic). The Port Forwarding function allows remote users to access services on your LAN such as FTP for file transfers or SMTP and
POP3 for e-mail. The DSL-3580L will accept remote requests for these services at your Global IP Address, using the specified TCP or UDP protocol
and port number, and then redirect these requests to the server on your LAN with the LAN IP address you specify. Remember that the specified
Private IP Address must be within the useable range of the subnet occupied by the Router.
To access the PORT FORWARDING settings window, click on the PORT FORWARDING button in the ADVANCED tab
PORT FORWARDING RULES CONFIGURATION
Select an application type, e.g. FTP, from the Application Name
drop-down menu for a pre-defined application to speed up configuration
or type an application name manually in the Name input box in order to
define your own application.
Select a name from the Computer Name drop-down menu or type an IP
address in the IP address input box to appoint the PC to receive the
forwarded packets.
The External Port shows the ports opened for remote users in the WAN
side of the router. The TCP/UDP means the protocol type of the opened
ports.
The Internal Port shows the ports opened in the PC with the appointed IP
Address. The TCP/UDP means the protocol type of the opened ports.
