    Step 3Enable dynamic NAT for the inside network:
    Step 4For the Translated Addr field, add a new network object for the dynamic NAT pool to which you want 
    to translate the inside addresses by clicking the browse button.
    a.Add the new network object.

    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. (See Figure 4-3).

    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 Figure 4-4.)

    Step 1Create a network object for the FTP server address:
    Step 2Define the FTP server address, and configure static NAT with identity port translation for the FTP server:
