Concept Guide

For information on the GRE tunnel configuration on the controller, see ArubaOSUser Guide.
In the Instant UI
To configure a GRE tunnel in the UI:
1. Click the More > VPN link at the top right corner of the Instant UI. The Tunneling window is displayed.
2. Select Manual GRE from the Protocol drop-down list.
3. Specify the following parameters. A sample configuration is shown in Figure 53.
a. Enter an IP address or the FQDN for the main VPN/GRE endpoint.
b. Enter a value for the GRE type parameter.
c. Select Enabled or Disabled from the Per-AP tunnel drop-down list. Enable this option to create a GRE
tunnel from each W-IAP to the VPN/GRE Endpoint rather than the tunnels created just from the master
W-IAP. When enabled, the traffic to the corporate network is sent through a Layer-2 GRE tunnel from
the W-IAP itself and need not be forwarded through the master W-IAP.
By default, the Per-AP tunnel option is disabled.

4. Click Next to continue. When the GREtunnel configuration is completed on both the W-IAP and Controller,
the packets sent from and received by a W-IAP are encapsulated, but not encrypted.
