4.7.2 UPnP NAT Traversal Function
The UPnP NAT traversal function will help to automatically setup a router if
the DVR connects to the internet via a router.
When a PC connects to a DVR not in the same local area network, a real IP
address and corresponding port number is required. However if the DVR is
behind a router, the communication between the PC and the DVR will be
transmitted back and forth by the router. The router will need to setup port
mapping (forwarding) before images from the DVR can be remotely viewed
on the PC. For each individual DVR, the setting needs to be done individually.
Imagine if there is tens or hundreds of DVRs. The setting will take a long time.
Fortunately, if the DVR has UPnP NAT traversal function, the setting of the
router will be done automatically when it is enabled. Just select <Yes> for the
menu item UPnP NAT Traversal in the UPnP setup menu and it will take care
of everything.
