As per the
44.137.0.1 and subnets:
Report is that the 44.137.0.1 GW is promptly pingable, but regarding
their subnet only the following are *correctly* pingable, namely:
44.137.24.5
44.137.40.1
44.137.40.10
44.137.40.2
44.137.40.20
all the other not.
Those addresses are not on the 44.137.0.1 gateway but on two different
private
gateway systems that advertise only those addresses.
I hope everyone correctly implements a "most specific route first"
policy that means that
traffic to such addresses goes to the indicated tunnel endpoint
(89.18.172.155 and 89.18.172.156)
while other addresses in the 44.137.0.0/16 network are routed to
tunnel endpoint
213.222.29.194. That should be no problem on e.g. a Linux system. For example, 44.137.41.97 should be pingable via that
endpoint. When
doing a traceroute,
you should see a couple more hops after the tunnel that are radio hops.
That IP address doesn't appear on the above list but it is positively
pingable:
root@ir0rm-7:/# ping 44.137.41.97 -c 4

The hamwan.org
remain unreachable
That one is reachable for me:
It goes via radio to our 44.137.0.0/16 gateway and from there over
plain internet (it is BGP routed).
You may have trouble trying to access this with some of the typical
tunnel setups because they provide no tunnel endpoint.
