Router DNS settings?

[hamensman]

Using Asus RT-AX58U v2 running Asuswrt-Merlin 3004.388.8_2-gnuton1.

So I can now access pi-hole on http://asusrouter.com:5080/admin :)

How would I change DNS settings on Asus router to force all traffic to pi-hole, since this is not a separate raspberry pi but instead within the router?

You just make the router advertise itself as the DNS, as far as I know you can use DNS director to force it in LAN.

I've done that section. In my case, changed 192.168.1.0/24 to 192.168.1.160 and lan to eth0.

I have Advertise router's IP in addition to user-specified DNS set to Yes.

Do I set Global Redirection to Router? What about a MAC address?

I never had Merlin firmware on my router so I don't exactly know what has to be set there, you might try asking about it on SNBforums. But I would say the global redirection is what you want.
