MAM59 Posted August 21, 2022 Share Posted August 21, 2022 this is correct the way it is. Obviously, you get V6 over a tunnel interface (the entries with prefix len 128, aka "single address"). They also assign you a /64 subnet to be used by your clients. BUT, you need to announce it to them using appropriate protocols like RADVD,RTADVD or something. As far as I know, UNRAID does not contain these tools. There was another guy with almost the same problem. Maybe you should read for getting more details. In my opinion, the main mistake is to let the tunnel end on UNRAID which is not really the best choice for this. Maybe you have a different machine in your net up and running which can handle this much better? Once R[T]ADVD is up in your LAN, all machines/VMs/Dockers will get their own V6 Address automatically. (Maybe your Router himself can do the job???) Quote Link to comment

(Maybe your Router himself can do the job???) my router has dhcp ipv6.all my devices got IPV6 address but unraid servers Technically, the router shows that the unraid server has obtained IPV6. but the UNRAID do not shows that in the network settings Edited August 21, 2022 by xenoblade Quote Link to comment

Ok, that's a non useable (local net only) address, but your ifconfig shows also, that there was a global address starting with 2408:... assigned too. even 2 of them, one point-to-point /128 (which is strange if this is not really a tunnel ?!?!?!) and one really global with a /64 prefix. This is just a gui problem because it only shows you ONE address and doe not even pick the good one. The kernel has no problem with this (in fact, it is normal and totally ok with V6 to have "many" addresses at the same time), depending on the target, it picks the correct address from the list and uses it as the origin address of a packet to that destination. the gui is mostly used for assigning static addresses, it does not help much for dynamic assignements via dhcp. So, there is nothing wrong with your box. Quote Link to comment
