Interaction between NAT and DNS

NAT and DNS can be combined in various scenarios involving load balancing. These scenarios can include additional load-balancing switches that operate at higher protocol layers (Layers 4 through 7). For example, a large bank might have many web servers with transactions load-balanced across them.

In these cases, the NAT configuration must be carefully considered to achieve the desired results. Discussion of DNS and load-balancing scenarios is beyond the scope of this guide.
