AX86U New Pihole

[Helios]

Hello,
My friend gave me an Pi 4B and i decided to try Pihole.
after all the Pihole installation I've changed some settings on My AX86U (Merlin) to use the Pihole DNS but at first i just changed the WAN DNS to the Pihole and found out that it's not the correct way and i need to change the Lan DHCP settings instead.
I would like some help figuring out if i changed the correct settings.
This is my current settings after the change:

WAN:

LAN:

Do i need to change anything else? I've also see some people change settings on the DNS Director Tab which mine is off, but i don't understand if that is recommended or not yet.
Also after changing to the settings above, some devices such as smart bulb on my guest network stopped working, weird thing that most of the devices that was previously on the guest network do work but only some stopped working even though i could see them connected in the Asus router app i couldn't control them anymore and had to move them back to the normal wifi network. any idea why it's happening or that's something that suppose to happen?
Thanks Ahead for all the help

Correct Pihole setup was discussed in perhaps >50 threads. Just use Search.

Your guest network (depending how it’s configured) might not allow access to other LAN (intranet) devices like the Pi-Hole IP, or the AP may be isolated (clients cannot see each other).

I've seen some threads and some say need to enable the DNS Director and change the settings there and some say not so I'm confused a bit.

Right intranet option is disabled in guest network, but that wasn't an issue before and some devices still work as before just some stopped.
Should i just move all to the normal network so they can go through Pihole aswell?
Mainly used the guest network for smart bulbs and wifi cameras mothing else.

One advantage of using DNS Director is catching those network clients who try to bypass the Pi-Hole by having their own fixed DNS server values.

Generally if you plan to use DNS Director, you would first enable DNS Director.
Next set Global Redirection to User Defined 1.
In the User Defined #1 field input the IP address for the Raspberry Pi Pi-hole device.
Next under Client List select (or input) the Raspberry Pi's MAC address into the Client MAC Address field and set Redirection to No Redirection, then click the "plus"/add icon on the right to add the entry to the Client List.
The select the Apply button at the bottom to save the changes.

You may need to reboot both the router and all network clients to ensure the changes you performed are properly used by the router and clients. If one is using the 3006.102.x firmware they can go the next step of using the Guest Network Pro profiles section under DNS Director to further route Guest Network Pro clients to use the main LAN Pi-Hole. One would set each Guest Network Pro profile to User Defined 1 then select the Apply button.

For those using the YazFi addon script for Guest Networks they can input the Raspberry Pi Pi-Hole IP address into the YazFi DNS field(s). This will allow the YazFi clients to use the Pi-Hole. Note that YazFi is not supported under the 3006.102.x firmware. It is 3004.386.x and 3004.388.x firmware only.
