2. Click in the “Allow Other Network Users to Control Broadband Router’s
Network Features” check box to enable UPnP and allow UPnP services to be
defined on any of the network hosts.
3. Click in the “Enable Automatic Cleanup of Old Unused UPnP Services” check
box to enable automatic cleanup of invalid rules. When enabled, this feature
checks validity of all the UPnP services and rules every five minutes. Any old
and not used UPnP defined service is removed, unless any user defined rule
depends on it. Since there is a maximum limitation on the number of UPnP
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 UPnP active, from the “WAN Connection Publication” drop-down list.
UPnP services are not deleted when disconnecting a computer without proper shut-
down of the UPnP application (e.g. messenger). Thus, if running a boingo, services
may often not be deleted, and will eventually lead to exhaustion of rules and ser-
vices, and no new services can be defined. In this scenario, the cleanup feature will
find the invalid services and remove them, preventing services exhaustion.
