Full NAT Load Balancing

In Full NAT based load balancing, the P333R-LB replaces the Virtual IP address of
the P333R-LB with the real IP address of the Real Server, as in Half NAT load
balancing. In addition, P333R-LB replaces the incoming client's IP address with a
user-configured Proxy IP (PIP).
For the commands to configure Full NAT based load balancing, refer to Proxy IP
(PIP) Commands on page 310.
Full NAT enables the P333R-LB to provide the following:
• Eliminates the possibility of traffic that entered via the P333R-LB from
bypassing the P333R-LB on return - The PIP-client IP translation has to be
performed by the P333R-LB. This ensures that even in complex networks, or
when the Clients and Real Servers are in the same network, the return traffic
from the Real Servers to the Clients always traverses the P333R-LB, and not
through an potentially existing alternative route. This is also true in situations
where the Real Servers are in the Public realm.
