Two weeks ago my ISP dumped a firmware update on my router. There may or may not be a connection, but I now get ony 18/20 from http://ipv6-test.com/. The comment is that my router or firewall is filtering ICMPV6.
Before I start complaining to my ISP, I would like to make sure that it is not due to some change on the part of ipv6-test.com.
Wilfred says he has the same message, but I would like some more comfirmation. Does anyone NOT get the "filtered ICMPV6" message from ipv6-test.com?
