Windows XP or Windows ME. Please refer to the User
Guide of your PC.
After you install UPnP in the operating system of a PC and
activate it in the router, applications on this PC (e.g. Microsoft
Messenger) can communicate via the Internet without
authorization. In this case, the router automatically implements
port forwarding, thereby facilitating communication via the
Internet. The task bar in the PC, in which UPnP is installed,
contains an icon for the DSL router. In a Windows XP system,
the icon is also shown under network connections. Click this
icon and the user interface of the DSL router appears.
Note
: When the UPnP function is active, system applications
can assign and use ports on a PC. This poses a security
risk.
