view status and other information used to examine performance and for troubleshooting.
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-2640B 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 directory
PORT FORWARDING RULES CONFIGURATION
Select a name from the Application Name drop-down menu for a pre-configured
application or type a name in the Name input box 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 Ports to Open box shows which ports you want to open on the router. The
TCP/UDP means the protocol type of the opened ports.
