Tracerout fails in last hop but succeed from last machine

0

I have 3 servers : A, B and C.

A = 10.1.52.100 subnetMask = 255.255.255.0 defaultGateway = 10.1.51.254
B = 213.56.106.137 subnetMask = 255.255.255.192 defaultGateway = 213.56.106.190
C = 213.56.106.197 subnetMask = 255.255.255.224 defaultGateway = 213.56.106.222

The 3 servers and in different network. C is a linux Machine From server A, I type this command :

tracert B

I get this result :

1    <1 ms    <1 ms    <1 ms  10.1.52.254
2    <1 ms    <1 ms    <1 ms  10.1.255.254
3     1 ms    <1 ms    <1 ms  10.1.255.63
4     6 ms     6 ms     7 ms  213.56.106.197
5  213.56.106.197  reports: Destination host unreachable.

C is the server with ip 213.56.106.197; from that server if I type the same command :

tracert B

I get :

Traceroute to 213.56.106.137 (213.56.106.137), 30 hops max, 60 byte packets
 1  213.56.106.197 (213.56.106.197)  2996.302 ms !H  2996.307 ms !H  2996.300 ms !H

Why cannot I reach server B from server A?

Are both servers using the same DNS servers? – Ramhound – 2015-01-02T19:03:44.857

Looks like incorrect subnet and gateway settings on C. – user3767013 – 2015-01-02T19:58:47.587

thanks you user3767013 i updated the question with details on settings for subnet and gateway. – clogic – 2015-01-05T10:54:10.797

Are 213.56.106.190 and 213.56.106.222 assigned to the same machine? It's not clear how this is supposed to work, which makes it very hard to figure out why it's not working. – David Schwartz – 2015-01-05T11:04:20.633
