Can you help me set up ipv6 in OpenWrt 21.02.0-rc2

[itachi]

I put the bsnl router in bridge and ipv4/ipv6 - When I put it in ipv4/ipv6 the nat option showed up but I didn't check NAT

I then set up PPOE in openwrt

but IPv6 test - IPv6/4 connectivity and speed test is a fail

If anyone here is successful, can you please share the screenshots of your openwrt settings from LAN to wan to wan6, all important settings.

Thank you

I am in Tamil Nadu. The BNG (PPPoE Server) that my router connects to is from Ericcson and hence I do not yet have IPv6 (only Juniper BNG's support IPv6 as per online reports). However these are my OpenWRT config settings for WAN PPPoE IPv6 :

ONT : Netlink HG323RGW (in Bridge Mode, EPON)
Router : TP-Link Archer A7 v5 (running OpenWRT 21.02.0-rc2, handles PPPoE)

/etc/config/network :

/etc/config/dhcp :

/etc/config/firewall - DHCPv6 Rules :

ONT Settings :

Can anyone inform how to use LUCI (GUI) in OpenWRT to get IPv6 working?
The Syrotech ONT is able to latch on to IPv6. The ONT and downstream OpenWRT can ping an IPv6 router.
However, none of the devices connected to the OpenWRT Router (via Wi-Fi) can ping an IPv6 server.

Basic information missing. How is your network setup? ONT bridge and PPPoE on router?

Oh Sorry.
The ONT (Syrotech SY-GPON-1110-WDONT) is in Route Mode. It is getting IPv6. If I enable the ONT's Wi-Fi and connect, then all downstream devices can ping IPv6.
PPPoE is not on OpenWRT Router (It is still on ONT). I still don't know how to setup PPPoE on the OpenWRT Router (v24.10) with MAC Address Cloning.
The OpenWRT Router gets IPv6. Its internal Diagnostics page can also ping to IPv6 addresses.
However, none of the devices connected to the OpenWRT Router can ping IPv6.

Were DHCP and DHCPv6 created separately?

@sloj
Yes, but I did not create the interfaces. OpenWRT Router OS has them setup like that.

Select extend prefix and check.

Selected Extend Prefix, Rebooted... Still no change.
