we planing to switch our websites Loadbalancer to Nginx. Currently it is a Pound LB with around 1000-2000 connections/s and all
Backend-Servers are in the same official Subnet. We want to make all Backend-Webservers private (192.168.x.x) and only the LB
with an official IP address and NAT to the backends. Is this possible with nginx? I only see examples with 127.0.0.1. Does NAT and routing use a lot more Load?

If I understand your question, you may set any addreses in upstream:

upstream backend { server 192.168.1.1; server 192.168.1.2; server 192.168.1.3; server 192.168.2.1; server 192.168.2.1; # and server 127.0.0.1; # and even server unix:/tmp/socket; }
