Hi, 
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?

Thank you
