P-2602H(W)(L)-DxA Series User's Guide CHAPTER 22 Universal Plug-and-Play (UPnP) This chapter introduces the UPnP feature in the web configurator. 22.1 Introducing Universal Plug and Play Universal Plug and Play (UPnP) is a distributed, open networking standard that uses TCP/IP for simple peer-to-peer network connectivity between devices. A UPnP device can dynamically join a network, obtain an IP address, convey its capabilities and learn about other devices on the network. In turn, a device can leave a network smoothly and automatically when it is no longer in use. See Section 22.2.1 on page 278 for configuration instructions. 22.1.1 How do I know if I'm using UPnP? UPnP hardware is identified as an icon in the Network Connections folder (Windows XP). Each UPnP compatible device installed on your network will appear as a separate icon. Selecting the icon of a UPnP device will allow you to access the information and properties of that device. 22.1.2 NAT Traversal UPnP NAT traversal automates the process of allowing an application to operate through NAT. UPnP network devices can automatically configure network addressing, announce their presence in the network to other UPnP devices and enable exchange of simple product and service descriptions. NAT traversal allows the following: • Dynamic port mapping • Learning public IP addresses • Assigning lease times to mappings Windows Messenger is an example of an application that supports NAT traversal and UPnP. See the NAT chapter for more information on NAT. Chapter 22 Universal Plug-and-Play (UPnP) 277
