4.4.2 Port Forwarding

This function is used to open ports in your device and re-direct 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.
