Hi all,
Thanks for sharing!
That's a very interesting troubleshooting utility.
And yet more useful when someone suggests a possible fix.
Is there anyone that could help me to understand what's the issue here ?
93.51.76.174 44.134.160.1 97 [ 3] dropped: no source gateway
93.51.76.174 44.134.160.2 178 [ 3] dropped: no source gateway
Regards,
Marco

That data is from the stats collector that the late Brian Kantor
wrote, which can be seen here:

The login uses the old gateways login credentials from when Jim Fuller
ran it. See:
https://mailman.ampr.org/mailman/private/44net/2020-January/010633.html
I highly recommend these rules:
# This prevents nested ipencap
iptables -t raw -I PREROUTING -p 4 -i tunl0 -j DROP
# This prevents a general loop
iptables -I FORWARD -i tunl0 -o tunl0 -j DROP
# Drops outbound unassigned IPs from looping though tunl0 via ipencap
# You Must add accept rules under this line to make exceptions
iptables -I FORWARD ! -s 44.92.21.0/24 -o tunl0 -j DROP
# ^ adjust to your subnet

The same question goes for 89.33.44.100. I dumped
it and found no
outgoing packets from other sources for your gateway.
Is it possible you actually capture some spoofing attempts?
Do you account for replies to requests that may be addressed to non-44
addresses via your tunnels, like ICM unreachable and similar?
