Certificates implementation in "SSL forward proxy client and server authentication" scenario.

Kevin - i think we didn't understand correctly here. I can make decryption on the client side - this is not a problem. The main question here is the F5 can act as a client for the server it will connect and use client cert to authenticate ? So 2 servers will connect to the F5 VIP (HTTPS will be included, no client cert auth, SSL Offloading will occur). Then F5 will establish new HTTPS session (with client auth cert) to the server and send the requests there from the 2 servers. As i know how to offload the client site i don't see anything regarding client cert auth on the server side (profile). So the question here is - if it's possible to use client cert auth on the server side (one client cert will be provided for the F5) ? Many thanks for any info on that.
