How to change DHCP Nameserver?

[chipperhead]

I've got an Asus AC-68U router and following a guide to set up Pi-hole on my network.

On the video I'm following he has a setting under his DHCP range to specify the IP of the Raspberry Pi, I'm not sure which setting to change on my router.

This is his

He enters the IP of his Raspberry Pi into DNS Server 1

On my DHCP server settings I have this, do I change something here?
Thanks.

Thanks I'll have a go.
The only other setting I can see which it might be is in WAN settings.

DNS server I would imagine, odd how there's only one box though, it's very often two or at least advises you to separate with a comma.

Worth a go at least and worst case is you just revert it.

Put it in the DNS server box on your first post

Awesome, thanks
