is there any working tutorial for unbound?
Do i need to explicit block the port 53 ?
Do i need a nat rule ?
How can i test if this is 100% working ?

i found several tutorials. what is the actually best working solution?

thx

this tutorial works for me, but how do i prevent traffic over port 53?

if there is any traffic on port 53 one of your clients is not using your opnsense dns
tcpdump -i wan_interface udp port 53

Check for working DNS over TLS
tcpdump -i vr1 tcp port 853

i think it works! :-)

@fabian would be great if you could move this to tutorials! regards rené

I'm not sure if it works, because in my case:

tcpdump -i vr1 tcp port 853
