Port Forwarding
This function is used to open ports in your device and re-direct data through
these ports to a single PC in your network (WAN-to-LAN traffic). It allows remote
users to access services in your LAN, such as FTP for file transfers or SMTP, and
POP3 for e-mail. The device receives remote requests for these services at your
public IP address. It uses the specified TCP or UDP protocol and port, and
redirects these requests to the server on your LAN with the specified LAN IP
address. Note that the specified private IP address must be within the available
IP address range of the subnet where the device is in.
