Unable to ping6 from server, but able to ping6 from outside server


#1

I don’t have much IPV6 experience yet, so I hope this is a simple configuration error.

I have IPV6 addresses assigned to eth0 and I can ping these addresses successfully from an independent server on the internet. However, I am unable to ping any external IPV6 address from within my server; I just get a timeout error:

ping6 2001:41d0:1:d87c::db:1

PING 2001:41d0:1:d87c::db:1(2001:41d0:1:d87c::db:1) 56 data bytes
— 2001:41d0:1:d87c::db:1 ping statistics —
5 packets transmitted, 0 received, 100% packet loss, time 4032ms

My routing table is as follows:

ip -6 ro

default via fe80::1 dev eth0 metric 1 mtu 1500 advmss 1440 hoplimit 4294967295

Any suggestions as to what the problem is?
