UPnP
UPnP is short for Universal Plug and Play, which is a networking architecture that provides
compatibility among networking equipment, software, and peripherals. This device is an UPnP
enabled Video Server. If your operating system is UPnP enabled, the device will automatically be
detected and a new icon will be added to “My Network Places.” If you do not want to use the UPnP
functionality, it can be disabled.
In addition, this device also provides UPnP IGD function for NAT traversal easily. Use NAT
traversal when your device is located on an intranet (LAN) and you wish to make it available from
the other (WAN) side of a NAT router. With NAT traversal properly configured, all HTTP traffic to
an external HTTP port in the NAT router will be forwarded to the device.
 UPnP: To enable or disable the UPnP service.

Friendly Name: Shows the friendly name of this device.

UPnP NAT Traversal: When enabled, the device will attempt to configure port mapping in a
NAT router on your network, using UPnP™. Note that UPnP™ must be enabled in the NAT
router first.
 Port Range: The port range which will be opened in NAT router.

External IP address: Show the IP address and port for WAN access through Internet. If NAT
traversal is configured successfully, user can use this IP address and port to access this
device. The external IP address is not shown in case NAT traversal function is failed.
