Notes:
• The port forwarding function changes a global IP address to a private IP address, and "Static IP masquerade"
and "Network Address Translation (NAT)" have this function. This function is to be set in a router.
• To access the unit via the Internet by connecting the unit to a broadband router, it is necessary to assign a
respective port number for each device and address translation by using the port forwarding function. For further
information, refer to the operating instructions of the broadband router in use.
