How to configure app to have ipv6?

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

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
