This feature is more commonly found in load-balancing appliances that contain a variant of a standard operating system such as UNIX or Linux.

By using source NAT in these designs, we force the server reply traffic through the load balancer. In certain designs there may be a couple of alternatives to using source NAT. These alternatives are to either use direct server return or to set the load balancer as the default gateway for the real servers. Both of these alternatives require that the load balancer and real servers be in the same broadcast domain or Layer 2 domain. Direct server return is discussed in detail later in this chapter under the section, Direct Server Return.

This will be the VIP that represents the server farm for Web application. Destination port. This will be 80, the standard, well-known port for Web servers, as the request is for a Web application.
