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:
tunl0 Link encap: IPIP Tunnel HWaddr inet addr: 44.165.25.232 Mask: 255.255.255.255 UP RUNNING NOARP MTU: 1024 Metric: 1 RX packets: 100704 errors: 0 dropped: 0 overruns: 0 frame: 0 TX packets: 71193 errors: 0 dropped: 0 overruns: 0 carrier: 0 collisions: 0 txqueuelen: 0 RX bytes: 15150482 (14.4 MiB) TX bytes: 8963045 (8.5 MiB)
I cannot ping 44.165.25.232 nor traceroute towards it. # ADDRESS LOSS SENT LAST AVG BEST WORST STD-DEV STATUS 1 100% 1 timeout 2 100% 1 timeout 3 100% 1 timeout
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.
# ADDRESS LOSS SENT LAST AVG BEST WORST STD-DEV STATUS 1 62.69.192.233 0% 1 42.3ms 42.3 42.3 42.3 0 2 100% 1 timeout 3 100% 1 timeout
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.
Here I have a problem, my command: [root@server ~]# tcpdump -v -s0 -n proto ipencap | grep 44.165.25 ... 23:09:06.745031 IP (tos 0x0, ttl 39, id 30037, offset 0, flags [none], proto: IPIP (4), length: 104) 169.228.66.251 > 62.69.192.233: IP (tos 0x0, ttl 48, id 0, offset 0, flags [DF], proto: ICMP (1), length: 84) 75.80.130.94 > 44.165.25.232: ICMP echo request, id 26187, seq 21126, length 64 ... My server does not respond to such a frame tunnel (Public_IP > 44Net_IP) ' 75.80.130.94 > 44.165.25.232:'
Tunnel (44Net_IP > 44Net_IP) I have no problems. ... 23:09:10.556700 IP (tos 0x0, ttl 235, id 16048, offset 0, flags [none], proto: IPIP (4), length: 60) 213.73.1.100 > 62.69.192.233: IP (tos 0x0, ttl 253, id 20086, offset 0, flags [none], proto: TCP (6), length: 40) 44.165.68.254.15928 > 44.165.25.232.14580: ., cksum 0x2cd8 (correct), ack 1031 win 1024 ...
Here is my problem with the tunnel (Public_IP > 44Net_IP)
