Hello,

I'm pretty new to the LVS configuration world, but I hear great things. I
am trying to setup a Director on a separate network than the Real Servers
in a proof of concept scenario.

The Director is on a private subnet & the Real Server will be using a
public IP address. I followed the tutorial at
http://www.ultramonkey.org/papers/lvs_tutorial/html/

Anyhow, the whole config & tcp dumps here:

## LVS Machine

net.ipv4.ip_forward = 1
