Meaning of status in Received column:

natblockSpoofed probe packets appear to be blocked by your local NAT or firewall rather than being rewritten with a public source address.

IPv4 Outbound Filtering Depth:

The tracefilter test found your host unable to spoof routable, non-adjacent source addresses through even the first IP hop.
Summary:
The results from all tests are aggregated to produce a summary "State of IP Spoofing" report.
