TrueNAS in IPv6-only/IPv6-mostly networks

TrueNAS General

Hi,

This suggests IPv6-only operation is supported: TrueNAS Facilitates the Transition to IPv6-Only

However:

  • Disabling DHCP and not setting an IPv4 static address while leaving auto configure IPv6 enabled results in no networking
  • You can set IPv6 name servers under System→Network→Network Configuration, but if you try to do the above change to disable DHCP you will be taken to another screen that marks IPv6 name servers as incorrect syntax
  • You can’t remove the IPv4 default route from the GUI
  • Not having an IPv4 default route causes Apps to fail initialisation
  • DHCP option 108 (IPv6-Only Preferred) is ignored

Is anyone running TrueNAS in an IPv6-only/IPv6-mostly network?

I am running TrueNAS 26 beta 1.

AFAIK, TrueNAS uses storj.io for their ISOs and updates.
storj.io does not support IPv6.
So my guess is that you would have to manually uplaod the update files.

If that is an issue it can be addressed with manual updates or NAT64 & CLAT, but it looks like one can’t even get that far.
