Using Dynamic NAT

Figure 6-15 NAT Rules and Global Pools using the Same ID on Multiple Interfaces
Multiple NAT Rules with Different Global Pools on the Same Interface
You can identify different sets of real addresses to have different mapped addresses. For example, on the
Inside interface, you can have two NAT rules on two different pool IDs. On the Outside interface, you
configure two global pools for these two IDs. Then, when traffic from Inside network A exits the Outside
interface, the IP addresses are translated to pool 1 addresses; while traffic from Inside network B are
translated to pool 2 addresses (see Figure 6-16). If you use policy NAT, you can specify the same real
addresses for multiple NAT rules, as long as the destination addresses and ports are unique in each ACL.
