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

Ok - i will try to clarify the problem (solution is in design phase so all recommendations are appreciated). 1 - there are 2 clients that will be connecting to F5 (HTTP is planned here) 2 - F5 has to connect to 1 server which requires client auth As i understand it correctly i can make 1 VIP with server SSL Profile (when there is no client auth required - this is ok) - but here i have the requirement to authenticate client (in this case F5) to the server. Any ideas how to solve this ?
