Check if UPnP feature is working with the following procedure. Click [Start]-[Control Panel]-[View network status and tasks]. Click [View full map]. Right click on [Gateway], and then select [Properties] in. UPnP problem. Discussion in 'Software' started by lightbulb42, Feb 4, 2014. TEST 6 - UPnP Framework Firewall Exception Check - PASSED TEST 7 - Adapter #0 - 192.168.1.3 - FAILED. It wants UPnP to search for movies. I thought it would be simple to set up UPnP on the NAS. Been fighting with it for days. Lightbulb42, Feb 24, 2014 #6.
Every web services must run on a port or else the service will be inaccessible. For example, when you visit a website, your web browser automatically connects to the web server using port 80 because that is the standard port registered in the IANA organization. It is also possible to configure a web server to run under a different port number such as 8080 and since the web browser connects to port 80 by default, you’ll need to instruct the web browser to visit the URL using the different port by adding the port 8080 at the end such as http://www.website.com:8080
Even if you are trying to host a temporary game server, connect to a CCTV, remotely access your router configurations, download media files using a BitTorrent client such as uTorrent, all of the actions mentioned above requires an open listening port for optimal usage and in some cases it won’t work at all if the port is closed.
Fortunately most modern routers already support UPnP whereby the router automatically opens and forwards the required port when it is triggered by the software, saving you the trouble of manually accessing your router settings to forward a port. The only problem is, how do you know whether the port forwarding either manually created by you or automatically through UPnP worked? Here we have 5 web services which you can use to test if the forwarded port is open or closed.
1. YouGetSignal Open Port Check ToolThe open port check tool by YouGetSignal is a fast and easy to use port forwarding tester. Upon visiting the website, it detects your external IP address and automatically embeds it to the remote address box for your convenience. You can find a list of commonly used ports at the right hand side and clicking on it will instantly check the status of the selected port. You can also quickly scan all of the provided common ports by clicking on the “Scan All Common Ports” located at the end of the list.

2. Ping.eu Port Check
Ping.eu is a well known site that offers free web based network testing tools such as a ping test, traceroute, DNS lookup, WHOIS, reverse lookup, proxy checker, bandwidth meter, network and network mask calculator, detect country by IP, unit convertor and finally a port checker. Using the port checker is as easy as either entering an IP address or hostname, followed by the port number and clicking the Go button. Your IP address is detected and shown at the top of the webpage. Clicking on it will transfer the IP to the appropriate box for your convenience.
Ping.eu offers a great alternative to YouGetSignal because both are able to provide results in real time on the page without actually refreshing the whole webpage.

3. WhatsMyIP Port Scanners
As mentioned earlier, a port scanner can also be used to test if a port is open or closed. The difference between a port scanner and a port checker is the port scanner is able to automatically scan a range of IP addresses whereas a port checker is commonly used to check a single port on a single IP address.
WhatsMyIP Port Scanners stands out by having 5 different categories to check on common server/game/application/P2P/Custom ports. An additional feature that is not normally found on other port checkers is the ability to select the connection time out. 3 options are available which is short (1 second), default (2 seconds), or long (10 seconds). For security purposes, WhatsMyIP Port Scanners only scans your IP address.

4. Network Port Scanner Tool
The Network Port Scanner Tool is a more advanced port checker if compared to the list mentioned above with two modes which is Normal and Advance. Basically the normal mode allows you to quickly scan a range of ports for an IP address while the Advance mode lets you choose the type of scan and ping with additional advanced options including detecting the operating system for the remote IP. The different scan modes especially the SYN Stealth is useful to scan a host with a firewall enabled.
Network Port Scanner Tool has accurately detected that I was running Microsoft Windows 7 Ultimate operating system during the test.

5. IPv6 Port Scanner
While most of the online port scanners or checkers will scan IPv4 addresses, here is one that scans connected hosts with an IPv6 global unicast address. 8 UDP ports are a must to scan while the 53 TCP ports can be excluded. You can also specify up to 4 custom TCP ports to be checked.
The scan results are displayed in real time using Javascript.
Visit IPv6 Port Scanner
Additional Notes: The above online web services are only used to test if an external source can connect to you using the tested port. To test a local connection, you can either use a port scanning software or simply type “netstat -a” in command prompt.
As you can see at the image above, the IP 0.0.0.0 means that the port 8888 is being listened on all IP addresses such as the localhost 127.0.0.1, private(internal) and public(external) IP addresses.

Universal Plug and Play (UPnP) is a set of networking protocols that permits networked devices, such as personal computers, printers, gateways, servers and mobile devices to seamlessly discover each other’s presence on the network and establish functional network services for data sharing, communications, and entertainment. UPnP is intended primarily for residential networks. No special device driver support is necessary, common network protocols are used (TCP/IP, HTTP, XML, SOAP). UPnP uses UDP port 1900 and TCP port 2869.
The UPnP technology is promoted by the UPnP Forum. Formed in October 1999, the UPnP Forum is an industry initiative of more than 1000 leading companies in computing, printing, networking, consumer electronics and home appliances. A huge library of UPnP resources is available at the website of the UPnP Forum.
UPnP was published as an international standard, ISO/IEC 29341, in December 2008.
The foundation for UPnP networking is IP addressing, either by DHCP or by AutoIP (zero configuration networking). The next step in UPnP networking is discovery, based on the Simple Service Discovery Protocol (SSDP). SSDP allows a device to advertise its services to control points, for example to media servers (Serviio) on the network. The next step is to learn more about the discovered device and its capabilities by retrieving the device’s XML description from the URL provided by the device in the discovery message. Now the control point can send actions to a device’s service using the Simple Object Access Protocol (SOAP).
An additional capability of UPnP networking is event notification, or eventing. The event notification protocol defined in the UPnP Device Architecture is known as General Event Notification Architecture (GENA). The final step in UPnP networking is presentation, usually by providing an URL of a webpage loaded in a browser.
UPnP AV is an audio and video extension of UPnP, referenced in specifications published by other organizations, including the Digital Living Network Alliance (DLNA).
Problems with UPnP are lack of authentication and vulnerabilities with the risk that UPnP devices can be accessed and/or manipulated by malicious web sites.
A complete set of open source tools for creating and testing UPnP solutions is provided by Intel. They include Device Spy, a generic control point, and Device Builder, a code generation tool. In all, there are 11 tools in this package that range from low-level debugging to full reference tools :
- Device Spy
- Device Sniffer
- Network Light
- Device Builder
- Device Relay
- Device Validator
- Service Author
- AV Media Controller
- AV Media Server
- AV Media Renderer
- AV Wizard
Network Light is a software model of an UPnP device to show the basic functions of the UPnP protocol. The light can be switched on/off or dimmed. The following snaps show how

Another UPnP test tool, called UPnP Inspector, has been developed by Coherence. The Inspector is an UPnP Device and Service analyzer, and a debugging tool, based on the Coherence DLNA/UPnP framework. It is loosely modeled after the Intel UPnP Device Spy and Device Validator.
