I have a PPPoE connection and I can change the IPv4 DNS, but I cannot block and change the IPv6 DNS. I need help to change
You want to block just IPv6 DNS, or do you want to halt all IPv6? For what purpose?
The reason I ask is that you may want to just disable IPv6 on your device.
Please do not start new threads about the same problem.
The original thread suggests that a bug may exist.
I want to block IPv6 DNS from ISP and use another DNS address
But, that's another topic, because it's another question
Add your preferred DNS servers to the WAN6 interface in LuCI and then run these uci commands over ssh:
uci set network.wan6.peerdns='0'
uci commit network
ifup wan6
When authenticating with PPPoE, an automatic IPv6 interface is created that cannot be edited.
OpenWrt needs to implement ISP IPv6 DNS blocking in a future update. This is not possible at the moment
Can you post your /etc/config/network file? I don’t use pppoe so I would like to understand your current config.

You can run:
uci set network.wan.ipv6='1'
uci commit network
This should disable ppp auto-creating wan_6, at least as far as I can tell from historical posts.

Yes, that is possible, however we cannot block IPv6 from the ISP in OpenWrt. Hope they release it in a future update
