Proxy Server HTTP Connect not encrypted

[markijones]

I have a network configuration with an Apache Http proxy server inside a DMZ, and with an OpenVPN server behind the inside firewall. I'm new to OpenVPN, and as far as secure encryption is concerned, I'm sure my configuration leaves a lot to be desired. But with this first time current configuration (see below) everything works fine, and I get the tunneling functionality that I want with the client being able to access machines behind the inside firewall.

My issue is that the initial HTTP Connect request (and response), which is port forwarded through the outside firewall to the Apache Http server, is in plain HTTP and not encrypted. I've tried various configuration changes, but I cannot get the client to initiate the HTTP Connect request with an SSL/TLS ClientHello. Is there someone who can point me to the correct client configuration to make this happen? Thank you.
