Understanding VPN Features
As IAPs use a VC architecture, the IAP network does not require a physical controller to provide the configured
WLAN services. However, a physical controller is required for terminating Virtual Private Networks (VPN)
tunnels from the IAP networks at branch locations to datacenters, where the Aruba controller acts as a VPN
concentrator.
When a VPNis configured, the IAP acting as the VC creates a VPN tunnel to an Aruba Mobility Controller in your
corporate office. The controller acts as a VPN endpoint and does not supply the IAP with any configuration.
The VPNfeatures are recommended for the following setups:
l Enterprises with many branches that do not have a dedicated VPN connection to the corporate office.
l Branch offices that require multiple IAPs.
l Individuals working from home and, connecting to the VPN.
The survivability feature of IAPs with the VPN connectivity of RAPs allows you to provide corporate
connectivity on non-corporate networks.
