Hi I have a problem with nm : it seems to get an ipv6 address from dhcp, but it doesn't use it. ip addr inet 192.168.0.5/24 brd 192.168.0.255 scope global wifi valid_lft forever preferred_lft forever inet6 *:*:*:*:*:*:8f3e:7de1/64 scope global noprefixroute dynamic valid_lft 86334sec preferred_lft 86334sec ip -6 route *:*:*:*::/64 dev wifi proto kernel metric 303 mtu 1480 fe80::/64 dev wifi proto kernel metric 256 (I replaced my ipv6 by * for privacy) Web sites like http://whatismyipv6.com/ say that I don't have an ipv6. I searched on the web, but nothing concluant. Any idea ?

If I'm not mistaken on how this works (in comparison with my setup) it looks like you're missing a default route. Try `ip -6 route add default via *:*:*:*::/64 dev wifi`. Regards, ~Celti

Try `ip -6 route add default via *:*:*:*::/64 dev wifi`.

Erm, my apologies for not double-checking my post, that should have been "*:*:*:*::1", not /64, for the (probable) ipv6 gateway. Regards, ~Celti

It works ! Now how can I automate this in nm ?

While I'm not certain (my IPv6 routing is handled by AICCU and not NetworkManager), I believe you just need to add that *::1 address as the IPv6 gateway in your connection information. Regards, ~Celti
