Introduction
This document provides a sample configuration for the Application Control Module (ACE) configured for
source Network Address Translation (NAT) while inserting the original client IP address in the HTTP header.
When using source NAT, the client IP address is not passed to the load balanced server. The insertion of the
Client IP address into the header allows the servers to see the IP that made the connection. The servers default
gateway points to the MSFC in the server VLAN. The only communication that needs to be load balanced
will pass through the ACE.
This sample uses two contexts:
the admin context is used for remote management and Fault Tolerant (FT) configuration
• 
the second context, C1, is used for load balancing
•
