Hi MArkuz, I tried as you wrote me and it works! To see if it was actually registered correctly I removed the static clients that I had manually entered in the dns area and after giving the command ipconfig / registerdns I found them in the list dynamically, so it works. I don’t have nessn dhcp6 at least i think, the server that distributes ip is neth7. I do not understand . I refer you to my configuration already exposed in the post a few days ago.
I saw that in this link you sent me it is recommended to change the management of the neth dns to the domain controller, which is always neth7 in the br0 interface of the AD.
