Auto Private IP Setup (NAT Traversal): The UPnP NAT Traversal function will help to setup the DVR to connect to the internet via
a router.
When a PC connects to a DVR that is not in the same local area network, a real IPO Address and corresponding Port Number is
required. However, if the DVR is behind a router, the PC and DVR will communicate through the router. To view images from the
DVR on your PC, the router will need to setup Port Mapping (Port Forwarding).
When UPnP NAT Traversal Function is enabled, the DVR will set the router automatically. To do this, check the [AUTO IP (NAT
TRAVERSAL)] box in the [UPnP] Menu.
