Hello i have several neewbie question.
I will expose what i want to do and hope somebody can says to me if it’s possible to do it with HAProxy.
If yes I will try to setup it in opnsense (as there is haproxy module).
Ok let’s deep in my need.
One HAProxy in front of several server (vm or not)
I have several domain or sub domain name link to one or several vm. Each (or group of) vm have it’s own Let’s Encrypt certificates. It’s important for me that is the vm that manage their own certificates.
In my case all domain name have only one public ip and each vm have a “private” ip on the lan behind the HAPROXY /opnsense.
A small ascii “art” to help. If i need to provide more information let me know. thx
