Create an IP group which has a list of Unified Access Gateway servers that need to be used for load balancing.
IP groups are comma-separated lists of IP addresses you can reference by profiles, policies, and logs. Since the same Unified Access Gateway servers are used as pool members in two different pools, you can the attach IP groups to the pool rather than directly attaching servers to the pool. Any configuration changes to the pool members such as addition or removal of servers, you must do the changes at the IP Group level.
