Yes, and no. A firewall is still a firewall if it is configured to have all ports open. The Linux kernel firewall is still active, even though its default configuration is, everything open.
My point is, for some reason there are some that are not configured to block incoming IPv6 by default. When that should be the standard home/consumer router default setting. Then the user can open ports to ips as they need them.
This is called a firewall
