We typically set up LVS load balancers to use LVS NAT -- in other words, 
setting up the load balancer as the default gateway for (at least) the web 
servers being load-balanced.  On the load balancer, that means:

[1] Enabling ip_forward
[2] Using 'masq' in ldirectord.cf, e.g.,

virtual=public-address:80
        real=app1:80 masq
        real=app2:80 masq
        # etc.
        #fallback=127.0.0.1:80 gate
        service=http
        request="ldirector.html"
        receive="Test Page"
        scheduler=wlc
        protocol=tcp
        checktype=negotiate

On the app servers, that means setting the load balancer as the default gateway.
