Hello,
I have just registered with this forum in order to join my complaints about MBAM Web Protection blocking IPv6 ping.
This topic saved me lot of headache since I was desperately investigating why my IPv6 ping did not work for external Internet sites
like ipv6.google.com. Of course test with http://test-ipv6.com/ has been done with 10/10 result.
The problem is alive regardless of DNS settings of my network interface cards (Ethernet, Wi-Fi): automatic, Google, Cloudflare or OpenDNS. I am running MBAM v4.2.1.
It is really strange that Malwarebytes team did not yet fix this
