4.3.4 Congure Port Mapping (NAT)
Two ways are provided for port mapping to realize the remote access via the cross-segment
network, UPnP™ (Universal Plug and Play), and manual mapping. UPnP™ can permit the device
seamlessly discover the presence of other network devices on the network and establish funconal
network services for data sharing, communicaons, etc. You can use the UPnP™ funcon to enable
the fast connecon of the device to the WAN via a router without port mapping.
Before You Start
If you want to enable the UPnP™ funcon of the device, you must enable the UPnP™ funcon of
the router to which your device is connected. When the network working mode of the device is set
as mul-address, the Default Route of the device should be in the same network segment as that
of the LAN IP address of the router.
Steps
1. Go to System → System Sengs → Network → Network Service → NAT .
