???

Where do you get fe80::768e:f8ff:fe61:e241 local link address in server1-main route table?

this is default from the provider as gateway .

i think the gateway of server is Link Local address .

should i change the default gateway to non link local address ?


any other suggestion u feel ?

You can use local link address of gateway but it might get problem.
I doubt IPv6 setting of eth0 on cliet, missing IPv6 address on eth0.
You can use tcpdump to find out different between server and client ping, watching packet content, such as source and destination IPv6 address.

why the client shoud have ipv6 on eth0 ?

it have ipv6 on the tunnel interface & loopback and both are pingable from the server.

the problem is the client send packet , then it reach the server , then it die there ......

how to troubleshoot what happened to it there to see if it is routing issue or other thing ?

i have put public ipv6 gateway to the server and the same issue
the client cant reach internet

here is the client traceoute :

root@ca:~# traceroute6 google.com
traceroute to google.com (2607:f8b0:400d:c06::65), 30 hops max, 80 byte packets
1 2602:ffd5:1:dddd:bbbb::2 (2602:ffd5:1:dddd:bbbb::2) 1.814 ms !H 1.809 ms !H 1.793 ms !H


anyhelp ?

This is why I ask you use tcpdump to compare both ping content.

any help ?

---------- Post added 09-20-15 at 01:34 AM ----------

could it be issue form provider ?

Based on tcpdump, main-server can't forward the ping to next hop because both source and destination is loop back interface. It could be network loop. You need assign a IPv6 address for eth0 on client.

this is so weird !!!

now i dont understand something ....

any ipv6 ip put it on interface eth0 of the server ...i can ping it form internet

anything not in eth0 on the server is unreachable from internet .

i guess something we didnt do

what do you think ?


like wrong routing or ? .....IDK !

What's weird? If you talk about server only, being able to ping eth0 IPv6 address is normal.
Do you talk about internal network, including client?

well ,
agian
routing between server-client is 100 in both directions

now regasrding to internet .


assume im a remote router that support ipv6

from that router i can only reach an ipv6 that are put to eth0 of the server only

no other ips i can reach them

so assume i want to put a subnet to loopback 0 of server ..i cant reach it from the remote router from internet

but the same subnet if i put it on eth0 ..i can reach it

i think here we need to focus on and see why that happen !!

In your network, only server is on plain network, client is on remote side and can be reach through tunnel only.
