This method is similar to the multiple port groups method except instead of dedicating a group of port numbers to each Unified Access Gateway appliance, it dedicates an individual VIP to each appliance in addition to the primary load balanced VIP. If you have two Unified Access Gateway appliances, then you would set up three VIPs. The primary Horizon protocol on HTTPS port 443 is load balanced to allocate the session to a specific Unified Access Gateway appliance based on health and least loaded. The secondary connections are then routed to the correct Unified Access Gateway appliance based on the following Load Balancer configuration table.
Unified Access Gateway Configurations for External URLs for this configuration are shown in the following table.

Advantages of multiple VIPs:
- Do not rely on source IP affinity
- Uses standard port numbers
Disadvantages of multiple VIPs
Requires an additional public facing VIP for each Unified Access Gateway appliance in addition to the primary load balanced VIP.
