I think I have it now. The problem or issue that I had to come to grips with is that you appear to no longer be able to have SSL connections to VirtualHosts. Just to confirm this I tried to install a Joomla site in one of the virtual host locations and use it SSL only and would not work.
A quick search and I found this post
. A few edits and creation of files and I can now use SSL on the VirtualHosts.
That did not solve all my issues though for the connection to the WHS box.
I created an SSL related file for the VirtualHost to connect to the WHS box (I image this would work for any other host on another computer) and created the files below.
ProxyPass / https://192.168.100.2/
ProxyPassReverse / https://192.168.100.201/
Please note that contrary to a previous post I have reintroduced "ProxyPerserveHost on".
I think I now have it working for remote access.
The downside is that when you go to your ClearOS Web based administration page the additional virtual hosts running on SSL showup.
Hope that helps any others who might be trying to do the same or similar thing.
