I have several domains, one server, and domain host and server provider both support IPv6. So I looked up the IPv6 address of my server, and added those AAAA records to the DNS of the domains.
I heard that IPv6 requires specific rules in iptables. I use UFW as frontend to iptables. I looked in /etc/ufw/ufw.conf, added the line "IPV6=yes" and reloaded UFW.
Now I'm wondering, do I need to do anything else? Is this correct? Do I need special rules added for IPv6?
