+NAT Load Balance
+----------------
+
+Advanced configuration can be used in order to apply source or destination NAT,
+and within a single rule, be able to define multiple translated addresses,
+so NAT balances the translations among them.
+
+NAT Load Balance uses an algorithm that generates a hash and based on it, then
+it applies corresponding translation. This hash can be generated randomly, or 
+can use data from the ip header: source-address, destination-address,
+source-port and/or destination-port. By default, it will generate the hash
+randomly.
+
+When defining the translated address, called ``backends``, a ``weight`` must
+be configured. This lets the user define load balance distribution according
+to their needs. Them sum of all the weights defined for the backends should
+be equal to 100. In oder words, the weight defined for the backend is the
+percentage of the connections that will receive such backend.

+Load Balance
+------------
+Here we provide two examples on how to apply NAT Load Balance.
+
+First scenario: apply destination NAT for all HTTP traffic comming through
+interface eth0, and user 4 backends. First backend should received 30% of
+the request, second backend should get 20%, third 15% and the fourth 35%
+We will use source and destination address for hash generation.

+  set nat destination rule 10 laod-balance backend 198.51.100.104 weight 35
