Hi Josh
44.0.0.1 is not reachable via ICMP traceroute.
Try a UDP traceroute, or even just directing a DNS query to that
address.
Nope. not working either, and would the traceroute stop somewhere
within german hamnet space if just 44.0.0.1 would not be responding to
icmp? Well you never know with ipip tunnels :-)
For all sceptics out here who belive I do not source nat correctly, see
the attached pcap of this specific DNS query from my true hamnet ip
address to 44.0.0.1.
I wonder, what happens when anyone else is tracerouting or pinging back
to me: 44.142.162.123 are you getting through? No, I don't filter ICMP,
they are useful for PMTU discovery and a lot of other things :-)
