I do not know if these frames arrive. Maybe my ISP blocks the frame 44Net from my server
and not released in the World?

Why me of
my network 44.165.25.0/24 do not have access to all the
>44.0.0.0/8 ??? I use encap.txt and tunnel:

I cannot ping 44.165.25.232 nor traceroute towards it.
# ADDRESS LOSS SENT LAST AVG BEST

However if I traceroute to any other IP within 44.165.25.0/24 I get at
least a reply from 62.69.192.233.

Eventually a routing or firewalling issue...
Can you ping and traceroute towards some 44/8 destinations. Try
44.161.255.3 and let me know the results. 44.165.25.232:'
Tunnel (44Net_IP > 44Net_IP) I have no problems.
