Port Forwarding 
This function is used to open ports on 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.
