Despite Online.net supporting FreeBSD, they don’t mention it at all in their IPv6 wiki page. After a bit of research, I found two posts about that. The first one uses WIDE DHCPv6 (also known as KAME DHCPv6, dhcp6c or dhcp6. Since this is the only functioning tutorial I found, I will write here the steps I did to get IPv6: Enable IPv6 on the console and get your DUID. Enable IPv6 on the NIC: ifconfig igb0 inet6 -ifdisabled accept_rtadv up Transform the DUID into a binary file (needed for dhcp6c): echo <DUID> | awk '{ gsub(":"," "); printf "0: 0a 00 %s\n", $0 }' | xxd -r > /var/db/dhcp6c_duid Add this in /usr/local/etc/dhcp6c.

I recently got a Dedibox from Online.net in order to move my Nextcloud instance over (need that storage!). Since I’m really interesting in FreeBSD these days, I decided to use it on this new server along with ZFS. FreeBSD 12.0-RELEASE only came out a few days ago so there is no installation option available on the online.net console yet. However, FreeBSD 11.1-RELEASE is available. The thing, it only allows to use UFS.
