Enforce DNS with Adguard Home on 22.245

Hello,

I am attempting to enforce dns routing through Adguard. I am using OneMarcFifty's video tutorial for help - https://www.youtube.com/watch?v=Q-xDtCxnD0Q

However, this tutorial was made for a previous version of openwrt when the "Custom Rules" firewall tab was still in use.

I wish to implement the equivalent of this rule:

iptables -t nat -A PREROUTING -p tcp --dport 53 -m addrtype "!" --src-type LOCAL -j DNAT --to  127.0.0.1:57
iptables -t nat -A PREROUTING -p udp --dport 53 -m addrtype "!" --src-type LOCAL -j DNAT --to  127.0.0.1:57

Could anyone advise on this?

https://openwrt.org/docs/guide-user/services/dns/adguard-home#dns_interception - brief rundown is there.

you will require the updated rules as per nft tables if you are using the new builds.

Note this only blocks/redirects regular DNS. you will require extra rules for DOH etc.
