• Advertisement Time To Live: The time to live for the advertisement is measured in hops
(steps) for each UPnP packet sent. The time to live hop count is the number of steps a
broadcast packet is allowed to propagate for each UPnP advertisement before it disappears.
The number of hops can range from 1 to 255. The default value for the advertisement time to
live is 4 hops, which should be fine for most home networks. If you notice that some devices
are not being updated or reached correctly, then it may be necessary to increase this value a
little.
• UPnP Portmap Table: The UPnP Portmap Table displays the IP address of each UPnP device
that is currently accessing the router and which ports (Internal and External) that device has
opened. The UPnP Portmap Table also displays what type of port is opened and if that port is
still active for each IP address.
