./ UNIVERSAL PLUG & PLAY
You can use Universal Plug and Play (UPnP) to support new devices without
configuring or rebooting the Gateway.
In addition, you can enable the automatic cleanup of invalid rules. When enabled,
this functionality verifies the validity of all UPnP services and rules every five
minutes. Old and unused UPnP defined services are removed, unless a user-
defined rule depends on it.
UPnP services are not deleted when disconnecting a computer without proper
shutdown of the UPnP applications, such as messenger. Services may often not
be deleted and eventually this leads to the exhaustion of rules and services. No
new services can be defined. The cleanup feature locates the invalid services
and removes them, preventing services exhaustion.

1. From the Advanced Advanced menu, select Devices Devices from the left pane and then
