In this example, all HTTP traffic received by the controller is redirected to the external captive portal server
group and load-balanced across the captive portal servers. All wireless client traffic with destination port 80 is
redirected to the captive portal server group, with the new destination port 8080.
The external servers do not necessarily have to be on the subnet as the controller. The policy that redirects traffic to
the external servers for load balancing is routed to the external servers if they are on a different subnet.
