12.3 Configure Port Mapping (NAT)
Two ways are provided for port mapping to realize the remote access via the cross-segment
network, UPnP™ and manual 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.
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.
Steps
1. Go to System → Network → TCP/IP → NAT.

2. Check Enable.
3. Select Mapping Type as Manual or Auto.
– Auto: If you select Auto, the port mapping items are read-only, and the external ports are set
by the router automatically.
– Manual: If you select Manual, you can edit the external port on your demand by clicking to
activate External Port Settings.
Note
● You can use the default port No., or change it according to actual requirements.
