install the PEFNG and PEFV license in the controller, as described in Chapter 27, “Software Licenses” . .
Configure the authentication server that will validate the username and password for the remote AP.
z Provision the AP with IPSec settings, including the username and password for the AP, before you install it at
the remote location.
ArubaOS supports multiple remote AP modes of operation. By default, the remote AP operates in standard
mode. This mode enables the virtual AP when the remote AP connects to the controller. The information in
this section assumes the default mode of operation. For information on remote AP modes of operation, refer
to “Advanced Configuration Options” on page167.
Configure a Public IP Address for the Controller
The remote AP requires an IP address to which it can connect in order to establish a VPN tunnel to the controller.
This can be either a routable IP address that you configure on the controller, or the address of an external router
or firewall that forwards traffic to the controller. The following procedure describes how to create a DMZ address
on the controller.
Using the WebUI to create a DMZ address
1. Navigate to the Configuration > Network > VLANs page.
2. Click Add to add a VLAN.
3. Enter the VLAN ID.
4. Select the port that belongs to this VLAN.
5. Click Apply.
6. Navigate to the Configuration > Network > IP page.
7. Click Edit for the VLAN you just created.
8. Enter the IP Address and Net Mask fields.
9. Click Apply.
Using CLI
vlan <id>
interface fastethernet <slot>/<port>
switchport access vlan <id>
interface vlan <id>
ip address <ipaddr> <mask>
Configure the NAT Device
Communication between the AP and secure controller uses the UDP 4500 port. When both the controller and
the AP are behind NAT devices, configure the AP to use the NAT device’s public address as its master address.
On the NAT device, you must enable NAT-T (UDP port 4500 only) and forward all packets to the public address
of the NAT device on UDP port 4500 to the controller to ensure that the remote AP boots successfully.
Configure the VPN Server
This section describes how to configure the IPSec VPN server on the controller. For more details, see Chapter 15,
“Virtual Private Networks” . The remote AP will be a VPN client that connects to the VPN server on the
controller.
Using the WebUI
1. Navigate to the Configuration > Advanced Services > VPN Services > IPSec page.
2. Select (check) Enable L2TP.
3. Make sure that only PAP (Password Authentication Protocol) is selected for Authentication Protocols.
