Chapter 10 NAT Examples and Reference
Examples for Network Object NAT
Inside Load Balancer with Multiple Mapped Addresses (Static NAT,
One-to-Many)
The following example shows an inside load balancer that is translated to multiple IP addresses. When
an outside host accesses one of the mapped IP addresses, it is untranslated to the single load balancer
address. Depending on the URL requested, it redirects traffic to the correct web server.
Figure 10-3 Static NAT with One-to-Many for an Inside Load Balancer
Procedure
Step 1 Create a network object for the addresses to which you want to map the load balancer.
hostname(config)# object network myPublicIPs
hostname(config-network-object)# range 209.165.201.3 209.265.201.8
Step 2 Create a network object for the load balancer.
hostname(config)# object network myLBHost
hostname(config-network-object)# host 10.1.2.27
Step 3 Configure static NAT for the load balancer applying the range object.
hostname(config-network-object)# nat (inside,outside) static myPublicIPs
