Command History
Usage Guidelines 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.
Note The nat server command has no effect when predictor forward is configured, because no servers can
be configured.
The source-mac value encrypts traffic for the SSL service and is specific to SSL devices. The
source-mac value 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 en cruption.
Examples This example shows how to specify NAT on the server:
