8.1 UPnP
Introduction
UPnP is designed to automate the installation and configuration of a home network as much as possible. This means that 
UPnP-capable devices can join and leave a network without any effort of a network administrator.
Supported Operating Systems
The following operating systems support UPnP:
•Windows 8
•Windows 7
•Windows Vista
•Windows XP
UPnP and the TG789vac v2
UPnP offers you the following functions:
• You can access the TG789vac v2 GUI on your local network without having to remember the address of the 
TG789vac v2. For more information, see “8.1.1 Accessing your TG789vac v2 via UPnP” on page 70.
• If you are using a PPP connection to connect to the Internet, you can enable/disable your Internet connection without 
having to open the TG789vac v2 GUI.
For more information, see “8.1.2 Managing your Internet connection via UPnP” on page 71.
• You do not have to manually create port mappings to run services on a computer. The automatic port configuration 
mechanism for UPnP-enabled games and applications will do this for you. If the application is UPnP-enabled, UPnP will 
create these entries automatically. For more information, see “8.2 Assigning services (HTTP, FTP,...) to a computer” on 
page 75.
If your computer is running Windows XP, you first have to install the UPnP component. For more information, see 
“8.1.4 Installing UPnP on Windows XP” on page 73.
