Outbound spoofing summary (from the client to our server) Source address type IPv4 Private - RFC1918 rewritten Routable ✔ received Largest spoofable neighbor prefix length /10
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.
Warnings:
- ⚠️ Your host is behind a Network Address Translation (NAT) router or firewall which rewrites the source addresses of the test traffic. To test your provider's network further, you must remove the NAT/firewall/router and connect directly.

no Packets spoofed from adjacent netblock were not received, probably due to blocking yes Packets spoofed from adjacent netblock were received yes Packets spoofed from adjacent netblock were received (but that netblock is within the source AS)
IPv4 Outbound Filtering Depth:
The tracefilter test found your host able to spoof routable, non-adjacent source addresses through the first 10 IP hop(s).Summary:
The results from all tests are aggregated to produce a summary "State of IP Spoofing" report.Feedback:
