I’m a a bit confused what to put where in the truenas dyndns client form.
I don’t have access to a FreeNAS server anymore, but I believe you need to add the zone name as Domänenname.
For the username, you can try
none. If that doesn’t work, try the password as username and leave the password fields blank.
Have you solved this? Because I would also be interested to get dynv6 running on truenas.
I have gone to Unraid. As TrueNas was too difficult for me. (Docker, settings, BSD)
On Unraid I have setup dynv6 on my Fritzbox, my Subdomains in the Fritzbox and SWAG [reverse-proxy) on my Unraid to get access to my containers. I don’t use ipv6, as the Fritzbox has some trouble with that. (https://avm.de/service/fritzbox/fritzbox-7490/wissensdatenbank/publication/show/3525_Zugriff-auf-HTTPS-Server-im-Heimnetz-nicht-moglich/)Using an A-Record works great.
Sadly, in the last few days, dynv6 just lost or removed my A-Record. I don’t know why it disappeared.
