Actiontec Broadband Router User Manual
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”
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.
