Missing wan6 firewall zone

Installing and Using OpenWrt
1

With a new OpenWrt 23.05.4 default installation I have 3 interfaces, lan, wan, wan6, but in the firewall zones I only have lan and wan, there is no wan6, is it included in the wan firewall zone?
Thanks

Note: OpenWrt is configured in IPv6 NDP-Proxy mode (relay mode), because my ISP doesn’t support IPv6 PD (prefix delegation)

That is normal, wann and wan6 interfaces are in same wan firewall zone.

Thank you very much, I appreciate the confirmation
