I tried the "Allow ICMP through Gateway from external networks" option in combination with " Allow ICMP through gateway" and "Gateway forwards pings" and it works as expected for me. Whenever I unchecked "Allow ICMP through Gateway from external networks" the ping6 packets are not forwarded from WAN to LAN anymore. Could you show / explain how your Interfaces are configured? Where are your icmp6 packets come from and where do they go?
