Hi. I have Home Assistant installed in a docker container on my Synology but I need it to work with Matter-Server which I have also installed. It turns out that matter devices only communicate through IPv6 and when I look at my container manager I see that for host, the IPv6 is disabled.
IPv6 is enabled on the Synology network interface so this is a docker/container manager set up issue.
Is there a guide for how to do this with container manager anywhere? I’ve see this guide for native docker Enable IPv6 support | Docker Docs but I am not sure now it relates to the Synology container manager version or even where the container manager files are located.
I’m also trying to get this to work, but have had no luck. This was the best guide I could find that walks through the end-to-end setup:
However I keep getting stuck running docker network create --ipv6 $NETWORK with the following error: Error response from daemon: could not find an available, non-overlapping IPv6 address pool among the defaults to assign to the network.
Seems like its a common issue from these 2 github issues, and may be fixed soon in Docker 27, but DSM is only using Docker 20 so far.
