A decade ago, I tried to configure OVH ipv6 and give up after an headhache to use an ugly /56. I never try again to deal with a /64 and an outside gateway since your mail. Then I tried again with a fucking headache. But thanks to you. I solved my misconfigured problem. Before you test, stay with your /56 and try to list the mac address of your default gateway with : # ndp -a You will see the MAC address you will need for your /etc/hostname.if (this is an example for the ip6 part) ... inet6 2607:5300:60:62ac:: 64 !route add -inet6 2607:5300:60:62ff:ff:ff:ff:ff/128 -link -static -iface ix0 !route add -inet6 default 2607:5300:60:62ff:ff:ff:ff:ff #replace XX:XX:XX:XX:XX:XX with the gw mac address : !ndp -s 2607:5300:60:62ff:ff:ff:ff:ff XX:XX:XX:XX:XX:XX proxy #EOF This will work as expected. Cheers,
