Added line number 84 & 86. HA Ports are commonly used for Network Virtual Appliances (NVAs) such as firewalls, VPNs, or SD-WAN devices, where defining individual load-balancing rules per port is not practical. Traffic is distributed per connection flow (5-tuple), and health probes are used to ensure traffic is sent only to healthy instances. Please note that HA Ports are not supported on Basic or Public Load Balancers and are not intended for typical web or application workloads that require port-specific rules.

The HA ports load-balancing rules help you with critical scenarios, such as high availability and scale for network virtual appliances (NVAs) inside virtual networks. The feature can help when a large number of ports must be load-balanced.
