Local SSL Certs Via PFSense

How can I setup local SSL certs for stuff that is not publicly exposed from pfsense. All my exposed services are using haproxy and acme package for pfsense and I was looking for a way to use the same for local certs

If you are HAProxy with a wildcard certificate then you can bind it to a local LAN interface for local services.

Thank you for taking the time to share your expertise with us. It is invaluable!

I wanted to add would this be used as well for the OpenVPN certs?
I am reviewing your OpenVPN video and walking through a test and saw that I needed to create those as part of the wizard.

In your video you already had a cert…so I was assuming it came from cert manager.

I have not tried using it with OpenVPN.
