|Egress spoofing summary|
|Largest spoofable neighbor prefix||none|
- Your host is behind a filtering Network Address Translation (NAT) router or firewall. The NAT is blocking spoofed traffic rather than rewriting the source address. To test your provider's network further, you must remove the NAT/firewall/router and connect directly.
IPv4 AS Route:
This test run probed the following paths in order to infer your ability to send different spoofed source packets. Each node in the graph corresponds to an autonomous system, i.e. different Internet service providers. NOTE: This graph does NOT show if an AS blocks spoofed packets, only the path taken by received spoofed packets. The IP Path Details are available for this run.IPv4 Adjacent Netblock Testing:
Your host (37.188.168.x/24) can spoof 0 neighboring addresses

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 Egress 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:
