IPv6 & Docker

I have Unraid configured for IPv6 in the network settings and that seems to be working fine. However, none of my docker containers are given IPv6 addresses and also show no IPv6Gateway when using docker inspect. Doesn't seem to matter if the container is using host, bridge, or br0 for its network. What could I be doing wrong?

Ah, ok. That makes sense. Does that setting reference the subnet that I've setup via my router (which is /64)?

 

Looks like I need to switch to a static address and manual settings to change the subnet. Will have to do that later when I'm home and have direct access to everything. Don't want things to go wrong while I'm remote. Thanks again for your help!

Follow-up question here as I'm digging into this. I'd prefer to stick with automatic IPv6 settings on Unraid. Should the subnet that is passed to Unraid be configured on my router? I'm using pfsense and it looks like it's a /64 mask everywhere I can find it. Totally possible I'm missing something there, so if it's really a pfsense question then I'll ask on their forums.

Ok. Quick update. I was trying to assign a reserved IPv6 address to my server (in pfsense) and may have done that wrong. After removing the reservation and using DHCP, I now see IPv6 showing up in the docker settings. But my containers are still not getting addresses assigned. Feels like progress, but maybe not. The subnet for Unraid still shows as /128, but now br0 is showing /64.

Shooga,

 

Did you get this to work?  If so, perhaps you can assist me in the settings.  I'm in the same situation.
