I am trying to create a tls link between two haproxy instances. Each instance is installed on a machine which have some apps that need to talk with each other using the proxy. I want the haproxy instances to handle the tls stuff in behalf of apps since I am using client authentication. Now, what I tried to do is to have a haproxy on the client side to listen on localhost interface but it seems not possible. How do I accomplish that; to have outgoing/incoming going through haproxy ?
