 If you have a newer model of Freebox please refer to [[docs:guide-user:network:ipv6:freebox|How to use OpenWrt behind a Freebox with IPv6 delegation]]. The method described on that page is more complex than the below and is stated not to work on a Freebox Crystal. If you have a newer model of Freebox please refer to [[docs:guide-user:network:ipv6:freebox|How to use OpenWrt behind a Freebox with IPv6 delegation]].

-As described in the page linked above, the Freebox Crystal is limited in it's IPv6 functionality. It is, however, able to function as a bridge for Router Advertisement, DHCPv6, etc. so the below explains how to configure OpenWRT to take advantage of that. Your local IPv6 boxes will obtain full public IPv6 addresses, but as they are behind the OpenWRT firewall can be protected if required (in fact, that is the case with default OpenWRT configuration at time of writing).+As described in the page linked above, the Freebox Crystal is limited in it's IPv6 functionality.
