How to configure app to have ipv6?

[LDM]

Hi everyone,
I’d like to configure Nginx and WireGuard with IPv6. Previously, I was using TrueNAS Dragonfish-24.04.2.5, and everything worked perfectly with both IPv4 and IPv6. However, after upgrading to ElectricEel-24.10.1, none of my apps have IPv6 connectivity.

How can I configure IPv6? My TrueNAS shell has IPv6 connectivity, as does my virtual machine. For communication between my apps and the VM, I’ve set up a bridge like this:

If anyone can explain how to enable IPv6 on my apps, I would really appreciate it.

warmly
P.S I have already test to put this
net.ipv6.conf.all.forwarding=1
net.ipv6.conf.all.accept_ra=2
here : /etc/sysctl.conf

iX confirmed that docker doesn’t officially support IPv6 in TrueNAS on a recent ticket about routable IPv6

Ipv6 docker support

Problem/Justification docker default configuration does not support ipv6 Impact Users who want/need to use ipv6 inside docker will get errors, and things generally won’t work. User Story A user can set up a docker service that depends on a remote ipv6 address which is routeable, and the service works. More details on: [NAS-131333] - iXsystems TrueNAS Jira I tried configuring the docker daemon.json like Jian A suggested, but the strange thing is that it broke ipv6 on the host system for me…

Looking on my side, I gave my server a IPv6 Address but on Docker Settings I can’t add a IPv6 Subnet to my docker settings, and only used the IPv4 address when the app started.

Though someone may know a bit further, I don’t normally use IPv6 on an internal network so don’t mess around much with it
