daemon

I have a Hercules vmware appliance, which is a micro-linux vm that runs the PEN daemon and acts as a server load-balancer. It takes any incoming request on the appliance's IP and routes it out to a number of alternate IPs.

The logs of the daemon show the true IP of the browsers hitting the website. The logs of the websites themselves (iis 6 and 7) only show the requester IP as being that of the load balancer.

The IT manager tells me that when we had a hardware appliance (serveriron XL) doing the load balancing, the web logs reflected the requester IPs accurately. Is there any way to get this resolved with the daemon, or will I be digging that out of the closet and plugging it back in?
