Port Mapping

Two port mapping methods are available: Universal Plug and Play (UPnP) and manual mapping. UPnP
enables the NVR to discover other devices on the network and establish network services such as
data sharing and communication.
This section describes how to use UPnP for port mapping. You may also configure port mapping
manually with UPnP disabled. To use UPnP in your NVR, you must enable UPnP in the router to
which your NVR is connected. With UPnP enabled for Network Address Translation (NAT), the ports
on the NVR can be mapped automatically to the router, and computers can access your NVR from
outside the LAN.
1. Click Menu > System > Network > Port Mapping.
2. UPnP is enabled by default. Select the desired mapping type from the drop-down list. To map
ports manually, select Manual and then set external ports for the router.
