I have to admit I dont have the most experience with IPV6. I try to keep it very basic when setting up, but still it seems like the router have issues with routing.

My scenario is I have a native 56 IPV6 network, and just put 56 in the WAN setup with DHCPv6 and it seem like it get the ipv6 info from the isp with no problem. I can ping the gateway address and on the ipv6 check I get 10/10 so its quite sure the IPV6 is working.

I also allowed ipv6 in the firewall, and enabled ipv6 in the settings and used tracked interface on the LAN interface.

Now here is the issue. On a client on the LAN network I can ping for example routerperformance.net, but on the router I cant ping it, it just times out, and it dont fallback to ipv4. (This is the mimugmail repo).

I am not sure where to start debugging IPV6, and I dont feel the best strategy is to turn it off if I want to start being future proof.

Maybe the first question is can any of you test pinging with ipv6 to routerperformance.net and its a problem on the domain, and not my router, and if you guys can ping it, can you suggest where to start debugging IPV6?
