Hi Saarbremer,
This is the answer on the ICMP Echo:
For me it looks like that I don't receive the IPv6 multicast to ff02::/16.
I can see the packets with tcpdump but not with tcpdump -p. So the kernel is dropping them already.

- is your gateway set as default gateway?You mean set to active? If so, I would say yes as it is working.
Quote
- is the gateway for WAN set to Auto?It was set to the GW of the ISP, I changed it now to auto.
Quote
- what does "cannot reach" mean? Ping or Connection to apllication or both do not work?The OPNsense is able to use IPv6, But the subnet of the LAN is not able to reach anything outside the /64.

- does firewall live view show blocked packetsI can see the traffic from LAN reaching the WAN interface.
- can you packet capture and see if there's any traffic at all?
This is the answer on the ICMP Echo:

-is you ISP ready? Mine told me IPv6 was working, except it didn't as they failed to deploy it to their routers.In general I guess yes. But I managed it only in the same /64 as the default GW so far.
