OVH and FreeBSD hosts with IPV6

So I struggled getting FreeBSD or MidnightBSD ipv6 working on OVH.Â  The instructions are a little off.Â  The prefixlen has to be larger than it's allocated (for 64 it needs to be 56) and this is because the gateway ip is not in the /64 block.Â  It won't route no matter what you do with static routes, fe80 link locals, etc.
