network virtualization and physical LB

Hi,

How do you add a pc in a Hyper-v virtual network (HNV) as a resource in a physical load balancen?

Let's say that i have 10 web servers in a HNV in subnet 192.168.1.0/24, and my load balancer in placed in the physical core network at 10.70.10.1, and i want to create a Load Balance VIP for alle servers in my HNV 192 network.

I use a citrix netscaler, and it does not look like its supports the NVGRE.

I know that there is a "network virtualization gateway", but how does that work? do i need to setup NAT from 192.168.1.x to 10.70.10.x, and then add the 10.70.10.x ip to my LB - it will require a 10.70.10.x ip for every ressource i need in my LB.
