IPv6 from WAN to LAN

[hannesk71]

I would like to allow some IPv6 traffic from WAN to LAN. I have tried Firewall rules but it does not work

What should I do? I did not find any hints from the docs

Firewall rules (on WAN) should be sufficient, provided your IPv6 is set up correctly and there is no other router between your OPNsense and the internet, blocking traffic.
Perhaps you should provide a little more information  :)
