[c-nsp] load balancing on downlinks

[Dave Lim]

For downlinks from 2 different ISP, you gotta be creative with your
DNS. I am using Radware linkproof for this purpose. Basically, the
private IP of your servers are NAT to 2 public ip (carrier X, carrier
Y).

And for those 2 public IP, it will be tied to an A record, so Radware
will be your dns server too. A lookup on the A record of the dns will
provide different IP from each carrier as it load balances.
