Virtual Mobility Controller and IAP-VPN

  • 1.  Virtual Mobility Controller and IAP-VPN

    Posted Mar 27, 2017 09:01 AM

    Hi,

     

    I try the VMC (Virtual Mobility Controller) 8.0.1 with IAP-VPN but don't work...

     

    i get the following error on security log :

    isakmpd[5126]: <103061> <5126> <ERRS> |ike|   IKE_CUSTOM_useCert: can't find Server-Cert

     

    Any idea ?

    This must be something to do with the fact that the x86 VMC doesn't have a TPM / factory cert.

     

    I'm getting exactly the same behaviour when trying to convert an IAP-207 to a RAP:

     

    From Controller:

    Apr 25 15:08:58 <isakmpd 103061> <5314> <ERRS> |ike| IKE_CUSTOM_useCert: can't find Server-Cert

    Apr 25 15:11:05 <isakmpd 103061> <5314> <ERRS> |ike| IKE_CUSTOM_useCert: can't find Server-Cert

    Get a feedback of TAC, need to try with custom certificate...

    Hello,

     

    It seems that IAP VPN is only supported on hardware controllers.

     

    http://www.arubanetworks.com/techdocs/ArubaOS_801_Web_Help/Web_Help_Index.htm#ArubaFrameStyles/IAP VPN Support/IAP_VPN_Support.htm%3FTocPath%3DArubaOS%2520User%2520Guide%7CInstant%2520AP%2520VPN%2520Support%7C_____0

     

     
    IAP VPN is supported only on hardware mobility controllers (7000 Series and 7200 Series) including controllers that are stand-alone or managed by Mobility Master. However, IAP VPN termination is not currently supported on virtual mobility controllers. Masters (Mobility Master and Master Controller Mode) do not support any AP termination including campus APs, remote APs and IAP VPN tunnels.

    Yes, it is only supported on hardware controller...

     

    but you can use GRE Tunnel !

    Hello there

    How can I start with GRE tunnel between IAP and virtual controler ver.8.3? Its not working for me.

    Please see the "ArubaOS 8.3.0.x User Guide.pdf" guide here:  https://support.arubanetworks.com/Documentation/tabid/77/DMXModule/512/EntryId/29620/Default.aspx  Download the PDF and go to Chapter 45 (page 1019), "Instant IAP-VPN Support" to get started.  There is a subsection called "VPN configuration" that describes how to configure IAP-VPN.

    There is only

     

    Starting from ArubaOS 8.3.0.0, IAP-VPN is supported on Mobility Controller Virtual Appliance by using default
    self-signed certificate (Aruba PKI). For Instant AP to establish IPsec connection with Mobility Controller Virtual
    Appliance, the controller presents a default self-signed certificate which is uploaded on the Instant AP using
    Activate.

     

    I will be nice to have a real example...

    Same problem here. Is there a certificate required to be deployed to the iaps? How would you do that by using Aruba Activate? Didn't found any rule which would fit for this requirement... Maybe we also need a 'crypto isakmp ca' installed on the vmc?

     

    Any advice would be really helpful.



  • 12.  RE: Virtual Mobility Controller and IAP-VPN

    Posted Oct 26, 2018 07:51 AM

    Hi,

    I was able to resolve without the certificate as follows:

     

    1. Create a user and password on the internal base of the controller (Configuration > Authentication > Auth Servers > All Server > Internal > User + "user+password+role_authentication");


    2. Create a "Shared Secrets" in VPN Services (Configuration > Services > VPN > Shared Secrets > IKE Shared Secrets + Subnet:0.0.0.0 | Subnet mask: 0.0.0.0 | Representation type: Text-based | "password");


    3. Converter the IAP to CAP mode (Can not IAP Mode Converter to RAP Directly);


    4. With the AP converted to CAP mode on the controller, RAP mode converter by placing as user information + IKE_PSK_Shared_Secrets (Configuration > Access Points > Campus APs > "Select AP Campus" > Provision > Remote_AP_Yes> Remote AP Authentication Method: "Pre-shared Key").

    Thanks @apaiva for your detailed workaround. But the custumor would require a solution which scales better to deploy muliple batches of IAPs for IAP-VPN.

    1. With this Virtual solution is suffering a lot .... Unfortunately I could only solve it that way. You can even batch convert IAP (cluster) to CAP, but CAP to RAP only individually.

       

       

    2. I have two open cases for virtual contoller:

      1. About Fallback mode for Wired ports (model IAP-205H and IAP-303H). Where LAN ports do not navigate in fallback mode;

      2. Navigation  problem when tunnel mode, when using ports aggregations in vmware.

    Suddenly, somebody can help me! :)

    For 2.2 (vmware), it is no a MTU issue ?

     

    And yes, if you are using RAP, it is better to use hardware controller...

    Posted Oct 30, 2018 01:07 PM

    Hi @alagoutte

     

    This MTU in the Conotroller configuration and vmware has already been adjusted by support Aruba

    Aruba:
    Configuration> AP Groups> "MyGroup"> Profile> AP> AP System> "RAP MTU" and "SAP MTU". Unsuccessfully.

    vmware:
    Edit Advanced vSphere Distributed Switch Settings

    Procedure:
    1. Log in to the vSphere Client and select the Networking inventory view;
    2. Right-click the vSphere distributed switch in the inventory pane, and select Edit Settings;

    3. Select Advanced to edit the following vSphere distributed switch settings.
    Unsuccessfully.

     

    Thanks for the sugestion.

    Regarding RAP, we can not buy hardware. No way.

    Where the port aggregation is used ?



  • 18.  RE: Virtual Mobility Controller and IAP-VPN

    Posted Oct 31, 2018 07:43 AM

    Hi @alagoutte,

     

    In the Controller there are no aggregated ports, we are only using the ge-0/0/0 interface. This aggregation is performed on the physical ports of the blade server (v-switch) where it has an internal v-switch to the network core switch (which has aggregation and vlan trunk all). Isolation has already been performed using only 1 v-switch interface, but the problem has not been solved.

    In this same client, there is a server with vmware (which is not a blade) where we perform the same settings restore (of that ArubaOS that is in trouble) and it works normally, without problem in the navigation of the device.

     

    att,

    Ok, it is very specific... need to see with TAC



  • 20.  RE: Virtual Mobility Controller and IAP-VPN

    Posted Mar 06, 2020 06:50 AM

    Is there any other way to set up the VPN that deploying certificates with Activate? Can be the certificates deployed with Airwave on RW mode? Is it mandatory to use Activate?



  • 21.  RE: Virtual Mobility Controller and IAP-VPN

    Posted Mar 06, 2020 07:40 AM

    You can deploy certificate using AirWave



  • 22.  RE: Virtual Mobility Controller and IAP-VPN

    Posted Mar 09, 2020 04:43 AM

    Do you know which certificate upload option is the one to be used? I already asked that before but noone replied. Is it the custom SSL cert?

    Thank you very much.



  • 23.  RE: Virtual Mobility Controller and IAP-VPN

    Posted Mar 09, 2020 05:52 AM

    for me, it is the Server Cert



  • 24.  RE: Virtual Mobility Controller and IAP-VPN

    Posted Mar 09, 2020 06:00 AM

    Thank you very much. Pity the config is not more straight forward on cert configuration for the VPN connection. I will give it a try as soon as the customer green lights the test.

    Hi JoseAngel, were you able to get this working? 

     

    Can you take me through what you did?
