Cisco ASA 5500 Series Configuration Guide using the CLI
Chapter30 Configuring Network Object NAT
Configuration Examples for Network Object NAT
hostname(config)# object network myPublicIPs
hostname(config-network-object)# range 209.165.201.3 209.265.201.8
Step2 Create a network object for the load balancer:
hostname(config)# object network myLBHost
Step3 Define the load balancer address:
hostname(config-network-object)# host 10.1.2.27
Step4 Configure static NAT for the load balancer:
hostname(config-network-object)# nat (inside,outside) static myPublicIPs
Single Address for FTP, HTTP, and SMTP (Static NAT-with-Port-Translation)
The following static NAT-with-port-translation example provides a single address for remote users to
access FTP, HTTP, and SMTP. These servers are actually different devices on the real network, but for
each server, you can specify static NAT-with-port-translation rules that use the same mapped IP address,
but different ports. (See Figure30-4.)
