This section describes how to set up the ILB connections to achieve HA by using the half-NAT topology. You need to set up two load balancers, one as the primary and the other as the standby. If the primary load balancer fails, the standby load balancer assumes the role of the primary load balancer.
The following figure shows the half-NAT topology for configuring the ILB connections to achieve HA.
