SHDSL Router Chapter 16 Universal Plug-and-Play (UPnP) This chapter introduces the UPnP feature in the web configurator. 16. 1 Universal Plug and Play Overview Universal Plug and Play (UPnP) is a distributed, open networking standard that uses TCP/IP for simple peerto-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. 16. 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. 16. 1. 2 NAT Transversal 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 Transversal and UPnP. See the Network Address Translation (NAT) chapter in your User's Guide for further information about NAT. 16. 1. 3 Cautions with UPnP The automated nature of NAT Transversal applications in establishing their own services and opening firewall ports may present network security issues. Network information and configuration may also be obtained and modified by users in some network environments. Remote Management 16-1 Prestige 792H G. SHDSL Router All UPnP-enabled devices may communicate freely with each other without additional configuration. Disable UPnP if this is not your intention. 16. 1. 4 UPnP and ZyXEL ZyXEL has achieved UPnP certification from the Universal Plug and Play Forum Creates UPnPTM Implementers Corp. ZyXEL's UPnP implementation supports IGD 1. 0 (Internet Gateway Device). At the time of writing ZyXEL's UPnP implementation supports Windows Messenger 4. 6 and 4. 7 while Windows Messenger 5. 0 and Xbox are still being tested. UPnP broadcasts are only allowed on the LAN. See later sections for examples of installing UPnP in Windows XP and Windows Me as well as an example of using UPnP in Windows. 16. 2 Accessing the Prestige Web Configurator to Configure UPnP Step 1. Make sure your Prestige hardware is properly connected (refer to instructions in Chapter 2). Prepare your computer/computer network to connect to the Internet (refer to the Preparing Your Network portion of the Quick Start Guide). Type "192. 168. 1. 1" as the URL. Type "admin" as the user name and "1234" (default) as the password and click OK. The main menu screen displays. 16. 2. 1 Configuring UPnP From the navigation panel in the main menu, click UPnP under Advanced Setup to display the screen shown next.
