Automatic OpenDNS

[almodovaris]

I want to check if this makes sense:

In Services / OpenDNS I have:

Filter DNS requests using OpenDNS : check
Do not alter system DNS server settings: check
Username <censored>
Password <censored>
Network <censored>

Test result    good

# cat /etc/resolv.conf
domain locallandomain
nameserver 127.0.0.1
nameserver 208.67.222.222
nameserver 208.67.220.220
nameserver 208.67.222.220
nameserver 208.67.220.222
search locallandomain

In Services / Unbound DNS /  DNS over TLS I have:

each of those four IPs
port 853
dns.opendns.com

Does it make sense? I.e. DoT to OpenDNS. Do I need a firewall rule to filter DNS calls or it does that automatically?

In Firewall: Diagnostics: Statistics / rules there is nothing with port 53, nothing with DNS, and nothing with domain.
