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 gateway 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.
