I don't know why you have IPs in the 172.21.193.0 network on the real-servers.
Want to fill us in?

I also don't know if you have 1 or 2 NICs on the director and how
you separate the real-server network from the client's network.
If you don't have them separated, icmp redirects from the director
will stop your VS-NAT setup from working. 

Check the HOWTO for testing whether you've properly isolated these
two networks.
