I got a server with XenServer 6.0.2 and this server has 3 nic with 3 different ip addresses, because I am using 3 different subnet The first 2 card are working and from the first 2 subnet I have access to internet, the third one is the problem. Basically the hosts in the last subnet can ping each and other but I if try to ping the gateway I got
Destination Host Unreachable
and is not finished here. Trying to ping the gateway outside the subnet I got
PING 184.108.40.206 (220.127.116.11) 56(84) bytes of data. From 18.104.22.168 icmp_seq=1 Time to live exceeded
What does it means? I saw the configuration of each host in the 3rd subnet and the nic interfaces is setup to use the 3rd card. Every host in the 3rd subnet has in the /etc/network/interfaces the right ip addresss for the gateway.
