Two way SSL authentication in Load Balanced Environment

Hi  All ,

We are planning to host a server farm behind a load balancer , one of which is a web service . This web service should use two way SSL authentication (both server and client mutually authenticate each other with their certs). Any idea how to do this ??

Load balancer - Brocade ADX 1000 is used , it supports SSL . But am clueless how to carry out client authentication with the web server mediated by a load balancer .Because SSL termination would happen at the Load Balancer , even if we enforce client authentication on the web server -only the load balancer will authenticate itself against webserver for all requests from the actual clients

Pl help

thanks
