PFsense/HAProxy - Letsecrypt for only some servers in network

Hello all,

Some of the web servers/webapps on my network have their own instance Acme/Lets Encrypt; whilst others don’t.
Is there a way of setting up HAProxy to use Acme with some of my servers but to pass through the enquiry to the others with their own implementation of Acme.

I have a feeling that I would have to set up two “shared front-ends”, but I’m not too sure.

Can anyone point me in the right direction?

Thanks
Nick

Not sure if there is a pass through option, never tried.
