Chapter 8 Using Advanced Settings
Universal Plug and Play (UPnP)
To access the UP n P settings perform the following:
1. Click Universal Plug and Play in the Advanced screen. The “Universal Plug
and Play” settings screen appears.
2. Click in the “Allow Other Network Users to Control Wireless Broadband
Router’s Network Features” check box to enable UP n P and allow UP n P ser-
vices to be defined on any of the network hosts.
3. Click in the “Enable Automatic Cleanup of Old Unused UP n P Services” check
box to enable automatic cleanup of invalid rules. When enabled, this feature
checks validity of all the
UP n P services and rules every five minutes. Any old
and not used UP n P defined service is removed, unless any user defined rule
depends on it. Since there is a maximum limitation on the number of UP n P
defined services (256), enable the cleanup feature if the limit is in danger of
being exceeded.
4. Select whether all WAN connections, or only the main WAN connection, will
have UP n P active, from the “ WAN Connection Publication” drop-down list.
UP n P services are not deleted when disconnecting a computer without proper
shutdown of the UP n P application (e.g. messenger). Thus, if running a boingo, ser-
vices may often not be deleted, and will eventually lead to exhaustion of rules and
services, and no new services can be defined. In this scenario, the cleanup feature
will find the invalid services and remove them, preventing services exhaustion.
