Thanks a lot, this works for me as well. To summarize: There are 2 possiblities for a setup:

1. 2 interfaces, 1 public, 1 private. The loadbalancer (lb) forwards te request to the webserver and the webserver sends its answer directly through the public interface. In this case the webserver needs a public IP and can therefore be accessed from outside (although you can close all incoming ports via iptables). In this case you have to assign the virtual public IPs to the loopback device.

2. LVS-NAT: In this case the request will be sent through the loadbalancer (as you described above). Here, I do not need any publi interfaces for the webserver. I guess, I also do not need to assign the public virtual IP to the loopback interface, right?
