Hi,

 

According to the article K13385: Overview of the Proxy SSL feature, The Proxy SSL feature provides the BIG-IP system the ability to optimize Secure Sockets Layer (SSL) traffic between the client and the destination server without having the SSL connection terminate on the BIG-IP system

So I think that Proxy SSL connections will be lost and can not be mirrored
