Apache RP replacement with mixed client SSL cert requirements

So I currently have an Apache 2.2 reverse proxy setup utilizing virtual hosts. In one of the virtual hosts I have a long list of plain proxypass directives just utilizing a standard frontend and backend SSL connections. These pass throughs require a username/password combo on the backend server.

Then, I have one connection where I utilize a location directive within the same virtual host so I could implement client ssl certificate on the front end. The client ssl certificate is required and I have another directive which matches the certificate DN_CN to a specific value or else it will not allow the connection.

How can I accomplish this same setup in LTM with this type of a mixed configuration with a single IP and virtual server?
