I can ping6 in router page and in ssh
I see ipv6 address being assigned to my laptop
Its a IPv6 ULA-Prefix (it is generated after first boot). You can check the address in "Global network options"
this one IPv6 ULA-Prefix:fdff:d12b:526b::/48
I've changed it with the ip from wan and now it works
so every time I have to do this
If you mean you can ping public IPv6 on OpenWrt; but LAN devices cannot, we'll need to see your config.
Please run the following commands (copy-paste the whole block) and paste the output here, using the "Preformatted text </> " button:
Remember to redact passwords, MAC addresses and any public IP addresses you may have

Remove that line.
It appears you're actually using TetheringWAN6 not wan6. Examine the ifstatus TetheringWAN6 instead. It is probably an LTE connection, which usually means the ISP gives you only a single /64 and have to use relay mode.
ip6assign is also not operative in a relay situation.

The wan status looks good. You have a single GUA /64 from upstream.
In relay configuration, the LAN interface only holds the usual LLA (fe80) IP. But lan clients will be advertised the IPv6 prefix that exists on the "master" (TetheringWAN6) and should have their OS pick up a GUA IP from the same /64. When each client first uses this IP, OpenWrt will install a /128 route to the client via lan. So ip -6 route show should show a single IP route for each client, and you should be able to ping the clients from the router on their GUA IPv6.
