For information on the GRE tunnel configuration on the controller, refer to the ArubaOS 6.5.x.x User Guide.
In the Instant UI
To configure a GRE tunnel:
1. Click the More > VPN link located directly above the Search bar in 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
a. Enter an IP address or an FQDN for the main VPN/GRE endpoint in the Host text box.
b. Enter a value in the GRE type text box.
c. Select Enabled or Disabled from the Per-AP tunnel drop-down list. Enable this option to create a GRE
tunnel from each IAP to the VPN/GRE endpoint rather than the tunnels created just from the master
IAP. When enabled, the traffic to the corporate network is sent through a Layer-2 GRE tunnel from the
IAP itself and need not be forwarded through the master 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 IAP and the controller,
the packets sent from and received by an IAP are encapsulated, but not encrypted.
