Ultra Monkey doesn't make a clear distinction between LVS-NAT and LVS-DR,
the two LVS routing mechanisms that is uses. Rather the documentation
concentrates on the topologies that can be created.
In any case if you want a LVS-NAT setup, with high availability then you
should look at the Highly Available, Load Balanced Service.
http://ultramonkey.org/ultramonkey-1.0.1/topologies/topology-ha-lb-4.html
My understanding is that you _can_ use LVS-DR with NT as I believe that
you can assign multiple IP addresses to a single physical interface, though
I'm not entirely sure how to get around the ARP problem as described
on http://www.linuxvirtualserver.org/
For reference a LVS-DR setup is described in the Ultra Monkey documentation
as a High Capacity, Highly Available, Load Balanced Service.
