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-321B 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
