DNS Errors On New OPNsense Config

« on: August 25, 2024, 11:13:02 pm »

I have my OPNsense configured to use Cloudflare DNS.
After running several tests, they all are picking up my ISP's DNS (AT&T).

What could the cause be, and what can I do to troubleshoot this?

Thank you for your response.
I have solved the issue. ✅
My IPv6 was misconfigured.
