    Why Router manufacturers do not implement DoH/DoT in firmware?

    I understand I can use merlin firmware for DoH/DoT, but just out of curiosity. It'll be a really nice security feature, which they can brag about. Its not like that they'll have to implement it from scratch, clients already exist. All they need to do is make sure it works with their firmware.

    What's the point of DoH/DoT

    I've been running Pihole with cloudflare doh proxy for sometime now. While it works ok, I've been considering ditching it for Asus-merlin built in dot with nextdns. But does DoH/DoT makes any difference. My ISP can still see the IPs i am communicating with and can do reverse dns lookup to see...

    WAN DNS vs LAN DNS

    I set up a Pi-hole in my home network and I just want to know where to put my Pi-hole's IP - should it be in my LAN DNS or in the WAN DNS of my router? If on the LAN, what should be then on my WAN DNS? And vice-versa, if it should be on my WAN DNS, what should be on my LAN DNS?

I use the following IPTABLES commands. The rule is added correctly to iptables. Are these rules correct and how...
