RBR20 service blocking blocks internal traffic
I have 3 piholes with unbound running on my internal network. I set up service blocks to only permit those 3 devices to connect to the internet via tcp/udp 53 and tcp 853 (DoH). But when I enable tho...
Thanks for giving it a shot. You're right, this is messed up. I suspect you're seeing traffic to CloudFlare and Google because they do DNS over HTTPS (tcp port 853). I guess the best we can do is block 853 and hope for the best.
Do better, Netgear.
My block was like yours, both 53 and 853. and my ping was v4 (I did not add the /6 parameter).
This just sucks.
