IPv6 ping not work

Hi guys, I've had IPv6 from my ISP and try to test but it return this error:

The domain got resolved so I think it's ping problem. Hope this fix soon :grin:

Is the interface you receive you IPv6 on part of the wan firewall zone? Can you provide your /etc/config/network and /etc/config/firewall files?

This actually a node in my large network (total 15 nodes). I tested on my main gateway and ping good. I think it's my fault.
This is my network config (everything is static):

I disabled dnsmasq, odhcp and firewall too (my main router handle all)

Okay. I managed to fix it. LuCI did not put the netmask at ip6addr setting :grin: this is LuCI problem :sweat_smile:
