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.
Go to Menu > Configuration > Network > NAT.
UPnP™ Settings Interface
Check Enable UPnP.
Select Mapping Type as Manual or Auto.
OPTION 1: Auto
If you select Auto, the port mapping items are read-only, and the external ports are set by the
router automatically.
You can click Refresh to get the latest status of the port mapping.
OPTION 2: Manual
