Selecting Certificates
If you are configuring a VPN to support machine authentication using certificates, define the IKE Server
certificates for VPN clients using IKE. Note that these certificates must be imported into the controller, as
described in Management Access on page 824.
1. Select the server certificate for client machines using IKE by clicking the IKE Server Certificate drop-down
list and selecting an available certificate name.
2. If you are configuring a VPN to support clients using certificates, you must also assign one or more trusted
CA certificates to VPN clients.
a. Under CA Certificate Assigned for VPN-clients, click Add.
b. Select a CA certificate from the drop-down list of CA certificates imported in the controller.
c. Click Done.
d. Repeat the above steps to add additional CA certificates.
Defining IKEv1 Shared Keys
If you are configuring a VPN to support IKEv1 and clients using pre-shared keys, you can configure a global IKE
key or IKE key for each subnet. Make sure that this key matches the key on the client.
1. In the IKE Shared Secrets section of the IPsec tab, click Add to open the Add IKE Secret page.
2. Enter the subnet and subnet mask. To make the IKE key global, specify 0.0.0.0 for both values.
3. Enter the IKE Shared Secret and Verify IKE Shared Secret.
4. Click Done.
Configuring IKE Policies
ArubaOS contains several predefined default IKE policies, as described in Table 78. If you do not want to use
any of these predefined policies, you can use the procedures below to edit an existing policy or create your
own custom IKE policy instead.
The IKE policy selections, along with any preshared key, must be reflected in the VPN client configuration. When using
a third-party VPN client, set the VPN configuration on clients to match the choices made above. In case the Dell dialer
is used, these configurations must be made on the dialer prior to downloading the dialer onto the local client.
1. Scroll down to the IKE Policies section of the IPSEC tab, then click Edit to edit an existing policy or click Add
to create a new policy.
2. Enter a number into the Priority field to set the priority for this policy. Enter a priority of 1 for the
configuration to take priority over the Default setting.
3. Select the IKE version. Click the Version drop-down list and select V1 for IKEv1 or V2 for IKEv2.
