9.2.6 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.

If you select Auto, the Port Mapping items are read-only, and the external ports are set by the router
automatically.
Steps:

2) You can click Refresh to get the latest status of the port mapping.
