⁠IPv6 Support in Docker

Before you proceed, you will need a very recent docker installation, version 20.10.2 or later, recently merged with this pull-request. Otherwise, manually set-up SNAT using ip6tables, or try the other 2 approaches.

To enable ip6tables handling, the experimental flag must be enabled. Put the following in /etc/docker/daemon.json or adjust to fit:

{
	"ipv6": true,
	"fixed-cidr-v6": "fd00:ffff::/80",
	"ip6tables": true,
	"experimental": true
}

Then, restart the docker daemon:

sudo service docker restart.
