9.2.11 Configuring NAT
Purpose:
Two ways are provided for port mapping to realize the remote access via the cross-segment network, UPnP™ and
manual mapping.
UPnP
TM
Universal Plug and Play (UPnP™) can permit the device seamlessly discover the presence of other network
devices on the network and establish functional network services for data sharing, communications, etc. You can
use the UPnP™ function to enable the fast connection of the device to the WAN via a router without port mapping.
Before you start:
If you want to enable the UPnP™ function of the device, you must enable the UPnP™ function of the router to
which your device is connected. When the network working mode of the device is set as multi-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. Enter the Network Settings interface.
Menu > Configuration > Network
2. Select the NAT tab to enter the port mapping interface.
