Have you tried DNS over HTTPS? https://homenetworkguy.com/how-to/configure-dns-over-https-dnscrypt-proxy-opnsense/

No, I haven't, but before trying anything new I would like to rule out any bad configurations I might have done myself since I'm no expert.

Yeah... unless you're doing something funky with firewall rules yourself, I think your ISP is blocking it. I assume if you use the ISP gateway instead of 1.1.1.1 in that command, it works?

Yup

[In System > Settings > General:]

Ever since I moved and changed internet provider I had to do this hacky thing to get DNS to work on my network.

This is the configuration I had before that didn't work with the new provider:

In System > Settings > General:

DNS Server:
10.10.0.1 (my opnsense instance)
1.1.1.1
8.8.8.8

Allow DNS server list to be overridden by DHCP/PPP on WAN (unchecked)
Do not use the local DNS service as a nameserver for this system (unchecked)

That was it, I had DNS resolution through Unbound DNS with no extra configuration, but this config did not allow for DNS resolution with the new provider.
I could ping IPs, but I could not resolve outside DNS.

Here's what I had to do to get it to work:

In System > Settings > General:

DNS Server:
192.168.101.1 (ISP gateway I got from Interfaces  overview, see image below)
10.10.0.1 (my opnsense instance)
1.1.1.1
8.8.8.8



I also had to add the ISP Gateway in Services > ISC DHCPv4 on every interface in order to get DNS working, here's an example:



I dealt with this in order to get the connection working, but I know it's wrong and I hate this solution.

Can someone help me diagnose this and help me do it the right way?
