I have a TP-Link TL-WR740N just lying around and I thought of using it to block ads and malicious sites, just like a PiHole. I was wondering if and how I can set up OpenWrt on my router to act just as a DNS server with a list of blacklisted IPs.
From what I understand, I should set up my modem (I have the credentials) to use my WR-740N router's IP as DNS Server. Then, set up the WR-740N's DNS to something I choose (like 1. or other), and set up a list of blacklisted IPs, but I might be wrong.
I have the following setup, and I wanted to know if this is possible.
Thanks in advance!
