I get 20/20 with a RFC4890 based ICMP filter set.
That confirms the problem is on my end. Thank you.
I just found the button to completely disable the IPv6 firewall. I get 20/20 with the IPv6 firewall disabled. I should have thought about that before, but I was stuck with a setting somewehere else that said "block ICMP". That did not make any difference...
I am a bit reluctant to complain with the ISP because their "standard" solution seems to be to send a new modem/router. That will almost certainly make me lose Dual Stack. This particular model is the only one configured for Dual Stack and it is being fased out. The newer models are configured IOv4 only for existing customers and DS-Lite for new customers...
Cheers, Michiel
