Subj : Filered ICMP6 issue... To : Tony Langdon From : Michiel van der Vlist Date : Tue Aug 14 2018 22:22:38 Hello Tony, On Tuesday August 14 2018 22:25, you wrote to me: MvV>> Have you tried to determine if it is indeed the router and not MvV>> the local firewall on the system doing the test? TL> Good point. I am using Windows Firewall. In the advanced setting of the Windows firewall I have the following settings for IPv6: - Allow PING - Allow Packet too large The rest is blocked. It may be too strict for RFC4890, but is is good enough for http://ipv6-test.com. What settings do you have?
