Use this command to enable server NAT. If server NAT is configured, the server address and port number in load-balanced packets are replaced with an IP address and port number of one of the real servers in the server farm.

The nat server command has no effect when predictor forward is configured, because no servers can be configured.

The source-macvalue encrypts traffic for the SSL service and is specific to SSL devices. The source-macvalue sends the request back to the SSL device for encryption, the CSM load balances to the server through the SSL encryption. This value supports back end encruption.

This example shows how to specify NAT on the server:

Cat6k-2(config-slb-sfarm)# nat server
