https://www.zenarmor.com/docs/network-security-tutorials/how-to-configure-dot-on-opnsense

getting stuck when i create my own fw rules and nat to stop 53 out

as i have a few fw rules, should i create the block for 53 at the bottom so its first or at the top

thanks,
rob

Firewall rules are processed from top to bottom, so top

thanks RamSense

doing this command on my opnsense

tcpdump -i vtnet0 port 853

should i replace vtnet0 with my lan or wan interface?

thats very wierd i made a floating rule to block 53 and it worked as i couldnt access any websites anymore but when i did a tcpdump on my lan interface on 53 i could see loads of activity so somethings wierd, so it looks like my DoT isnt working

thanks,
rob
