Universal Plug and Play What is Universal Plug and Play? How do I know if I'm using UPnP? UPnP and ZyXEL ZyXEL has achieved UPnP certification from the Universal Plug and Play Forum Creates UPnP™ Implementers Corp. (UIC). 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. Please see your Users Guide for examples of installing UPnP in Windows XP and Windows Me as well as an example of using UPnP in Windows. 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:
Windows Messenger is an example of an application that supports NAT Traversal and UPnP. See the Network Address Translation (NAT) chapter in your User's Guide for further information about NAT. Are there any cautions about UPnP? All UPnP-enabled devices may communicate freely with each other without additional configuration. Disable UPnP if this is not your intention. |

Enable the Universal Plug and Play (UPnP) Service |
Select this check box to activate UPnP. Be aware that anyone could use a UPnP application to open the web configurator's login screen without entering the Prestige's IP address (although you must still enter the password to access the web configurator). | |
Allow users to make configuration changes through UPnP | Select this check box to allow UPnP-enabled applications to automatically configure the Prestige so that they can communicate through the Prestige, for example by using NAT traversal, UPnP applications automatically reserve a NAT forwarding port in order to communicate with another UPnP enabled device; this eliminates the need to manually configure port forwarding for the UPnP enabled application. | |
Allow UPnP to pass through firewall |
Select this check box to allow traffic from UPnP-enabled applications to bypass the firewall. Clear this check box to have the firewall block all UPnP application packets (for example, MSN packets). | |
