ping 2001:6f8:306::1 from 2001:6f8:306::11 -> works fine ping 2001:6f8:202:202::2 from 2001:6f8:306::11 -> works like pinging www.ipv6.org (i.e. only works when pinging 2001:6f8:306::1 at the same time)

kaname$ ip -6 r g 2001:6f8:202:202::2
2001:6f8:202:202::2 from :: via 2001:6f8:306::1 dev eth0 src 2001:6f8:306::11 metric 1 expires 21325591sec mtu 1500 advmss 1440 hoplimit 4294967295

ping 2001:6f8:306::11 from 2001:6f8:306::1 -> works fine

root@nadia:~# sysctl -a | grep ipv6 | grep forwarding 

net.ipv6.conf.eth0.forwarding = 1
net.ipv6.conf.sixxs.forwarding = 1
net.ipv6.conf.default.forwarding = 1
net.ipv6.conf.all.forwarding = 1
net.ipv6.conf.lo.forwarding = 1

Do you need help?X

it's not a firewall issue (I tried with no rules and all default policies to ACCEPT)

I don't see what's wrong with my setup.

Anyway thanks for your reply.
