Port Forwarding
This function is used to open ports in your device and redirect data through those
ports to a single PC on your network (WAN-to-LAN traffic). It allows remote users
to access services on your LAN, such as FTP for file transfers or SMTP and
POP3 for e-mail. The device accepts remote requests for these services at your
global IP address. It uses the specified TCP or UDP protocol and port number,
and redirects these requests to the server on your LAN with the LAN IP address
you specify. Note that the specified private IP address must be within the
available range of the subnet where the device is in.
Choose Advanced > Port Forwarding. The page shown in the following figure
appears.
