Https over CludflareD Tunnel with custom Comodo SSL Certificate?

What steps have you taken to resolve the issue?

Hello,

I have read many similar topics but none of them helped me.

I apologize that my question doesn’t meet the templating requirements for this category.

How do I configure Https through CludflareD Tunnel with my custom Comodo SSL Certificate.
I have been working fine with Universal SSL for a long time, but now I need to use my own Comodo SSL Certificate. And buying Business subscription to manage custom certificate is too expensive for me.

I will have the following design
Cloudflare DNS => CloudflareD Tunnel => Proxy with Comodo SSL Certificate => Applications

And currently this working for me.
Cloudflare DNS with enabled Universal SSL => CloudflareD Tunnel => Http Proxy => Applications

So I have the following questions.

  1. Which SSL/TLS encryption mode should I choose for this?
  2. I understand I need to disable Universal SSL so that Cloudflare does not generate a certificate for me. Is that correct?
  3. DNS Records what should be the Proxy status? Proxied or DNS Only?
  4. What else do I need to configure so that I can see my site through https://mysite.com with my Comodo SSL Certificate?

Thank you very much for the tips and help.
