IPv6: Is CSF working?

[netizen]

I have installed (latest) csf on a Proxmox server (Debian 7.4) and I want to start using ipv6 (which is enabled on the server with a /64 subnet.

My ipv6 settings in CSF:

IPV6 = 1
IPV6_ICMP_STRICT = 1 (to disallow incoming ICMP via ipv6)
IPV6_SPI = 1

I am pinging my server however from a remote site ( http://www.subnetonline.com/pages/ipv6- ... 6-ping.php)

and I getting a normal response (0% loss)

Why?
Does this mean that CSF is not working on IPV6 connections?
Unfortunately I do not have an IPv6 ISP to make further tests from my side, so I am vey worried that the server is not protected!

Any advise is welcome!

The IPv6 configuration does not restrict IPv6 ping requests and IPv6 heavily utilises ICMP packets for data control.
