9.2.7 Configuring NAT Settings
Two ways are provided for port mapping to realize the remote access via the cross-segment network, UPnP™ and
manual mapping.
UPnP
TM
Purpose:
Universal Plug and Play (UPnP™) permits the device to discover the presence of other network devices on the
network seamlessly 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:
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 UPnP™ interface.
3. Check checkbox to enable UPnP™.
4. Select the Mapped Type as Manual or Auto in the drop-down list.
Task1: Auto
If you select Auto, the Port Mapping items are read-only, and the external ports are set by the router
automatically.
Steps:
1) Click Apply to save the settings.
2) You can click Refresh to get the latest status of the port mapping.
