Depends how your network is configured. If your real IP is and 
your internal range is, then your traffic to the real 
servers will be entirely on so as long as you're not doing any 
NAT of that traffic you should be okay.

What about using the real IP didn't work? Where did the packets end up?

The VIP for DR is your external IP.

It would be helpful if you slimmed down your config to one real server 
and maybe ran tcpdump on it so you can see if traffic is even making it 
to the backend.
