double authentication with check CN serial number and certificate authority

Hi Jean_Mamène,

take a look at this knowledge base article: K13452: Configure a virtual server to serve multiple HTTPS sites using the TLS Server Name Indication feature.
You can use it to assign a specific SSL profile that requires client cert auth to the host you want to authenticate. 

Please pay attention to URL, Host, FQDN and other terms. It makes discussions here in devcentral much easier when the correct terms are used.
