Spoof status key received Spoofed packet was received. ✔ Pattern of tests from this IP block indicates a switch from allowing spoofing to blocking it. rewritten Spoofed packet was received, but the source address was changed en route. blocked Spoofed packet was not received, but unspoofed packet was. unknown Neither spoofed nor unspoofed packet was received.

Meaning of status in Received column:
natblock Spoofed 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.Feedback:
