Ssl – Apache ~ how to force SSL client auth for specific IP

Haven't been able to figure out how to easily manage access to my SSL website.

I'm trying to allow access to a specific location based on client IP.

If client IP = 192.168.x.x => bypass client certificate authentication
If client IP !=192.168.x.x => request client certificate authentication.

I tried several method (URL rewriting, Vhost, Allow,deny,satisfay…. without success..)

My SSL client verification works OK, I'm just stuck with this basic "if" request. I'm running Apache 2.12.

I already tried to implement http://httpd.apache.org/docs/2.0/ssl/ssl_howto.html (section How can I require HTTPS with strong ciphers and either basic authentication or client certificates for access to a subarea on the Intranet website for clients coming from the Internet but still allow plain HTTP access for clients on the Intranet?) but it's not working ..

Quite frustrating because this is exactly what i'm looking for 😉 (except for the authtype basic)

Thanks
