You should be able to ping the HA. I had issues some time ago to
reach other nodes on the home network: proxy ND was not enabled
(/proc/sys/net/ipv6/conf/*/proxy_ndp) on some interface. Even if it is
certainly unrelated, can you check it is already enabled. Can you also
confirm that your firewall rules allow ICMPv6 (INPUT).
