Traffic Flow from AP to CALEA Server through VPN
You can also deploy the CALEA server with the controller and configure an additional IPsec
tunnel for corporate access. When CALEA server is configured with the controller, the client
traffic is replicated by the slave AP and client data is encapsulated by GRE on slave, and
routed to the master AP. The master AP sends the IPsec client traffic to the controller. The
controller handles the IPsec client traffic while GRE data is routed to the CALEA server. The
following figure illustrates the traffic flow from AP to the CALEA server through VPN.
