Can't ping LAN interface over IPv6

[pagefault]

Hi,

I am using OPNsense 23.7.10 and I am currently in the process of setting up IPv6. I have a /56 prefix from my ISP, and a /60 prefix is delegated to OPNsense via ISP router. I set up DHCPv6 and set Router Advertisements to "Managed".

My LAN devices get global IPv6 addresses. The problem is they can ping each other, but neither the LAN nor WAN interface of OPNsense nor anything beyond.

What could be the problem here?

EDIT: I have a floating rule which allows ALL IPv6 traffic. I can see the Ping reaches LAN and Loopback.
