HAProxy Redirect with Lync 2013

Hey guys, first off, love HAP. With that said, I am having a little issue with it working properly with Lync 2013, we have made SEVERAL attempts and different alterations to the config and we still can’t seem to get the lync server to accept the connection after the proxy passes the traffic. Has anyone worked with Lync 2013 and HAP at all, if so…please help.
