IKEv2 AnyConnect and pool allocation via RADIUS

I set up a CSR1000V (03.09.00a. S.153 - 2.) for AnyConnect with IKEv2. I store the user name and the IKEv2 permission policy on the RADIUS server. The customers are placed in their own iVRFs through the broadcast on the NAS RADIUS attributes.

for example, in FreeRadius (2.1.12), what follows is defined (home is the 'group') as [email protected] / * / format.

Home-password in clear text: = "cisco".

Cisco-AVPair += "ip:interface - config = vrf forwarding CUST-A."

Cisco-AVPair += "ip:interface - config = ip unnumbered loopback100."

Box-pool = "CUST-A-POOL '.

[email protected] / * /               Password in clear text: = 'test123 '.

The user and group permission information are then merged and cloned on the virtual model:

Crypto ikev2 name-mangler EXCERPT-GROUP

EAP suffix delimiter @.

!

Ikev2 crypto FlexVPN-IKEv2-profile-1 profile

fvrf IPSEC-FVRF game

match the key - remote identity FlexAnyConnect id

identity local dn

authentication eap remote query-identity

authentication local rsa - sig

PKI trustpoint cacert.org

DPD 60 2 on request

AAA authentication eap List1-AuthC-FlexVPN

AAA authorization eap group list mangler-name-FlexVPN-AuthZ-list-1 EXCERPT-GROUP

AAA authorization eap user set caching

virtual-model 1

!

type of interface virtual-Template1 tunnel

no ip address

ipv4 ipsec tunnel mode

VRF tunnel IPSEC-FVRF

Profile of tunnel FlexVPN-IPsec-profile-1 ipsec protection

However, it appears that the attribute RADIUS specifying that the pool is ignored; I can see the attribute RADIUS (IETF 88) broadcast on the NAS in the RADIUS debugs:

* 21:36:39.384 August 16 TSB: RADIUS: box-IP-pool [88] 13 'CUST-A-POOL'

However, cryptography debugs say an IP cannot be attributed:

* 21:36:39.435 August 16 TSB: IKEv2: cannot allocate an IP addr

Contents of payload:

AUTH NOTIFY (INTERNAL_ADDRESS_FAILURE)

If the framed pool is removed and a box-IP-Address instead of the user, the address set is assigned. The CUST-A-POOL is set locally on the NAS server. Is that all that I'm missing? Any debugs more detailed can be generated?

See you soon,.

  • A problem when authentication via Radius ASA

    Hi all

    Please give me a helping hand. I have a problem when through ASA 5520 via Radius Authentication for ACS 4.0 via the VPN device. I need to configure secure authentication and NAC for remote user VPN. It simply does not work, but it works when you use Ganymede so all the connection seems to be ok as ACS succesfully authenticate a remote via MS AD VPN user when you use Ganymede. But I read that I can not use NAC when Ganymede using, I'm good? ASA and ACS journals indicate a problem with the shared key but I already double checked the key on both sides, the IP address is correct on SAA and I also tried all possible methods of RADIUS on SAA. Any idea where might be a problem?

    Hello

    When you use ACS 4.0, then make sure that the AAA Client for ASA entry you created on GBA, if under a NDG, then make sure that there is no key to the NDG level.

    Otherwise, pass entry client ASA as RADIUS ACS in NDG (Unassigned) on ACS.

  • Type of cert for ikeV2 anyconnect

    Hello world

    I created the CSR for anyconnect IkeV2.

    When I ask the seller to cert that I should ask them what type of certificate that I needed for IkeV2?

    We do not want users to use ssl as https://xyz.com and to connect and download the client.

    We want machine pre installed with anyconnect and profile users and connect using IkeV2.

    Concerning

    Mahesh

    Each certificate provider has their own list of choices. Many understand Cisco among their choices. that is to say:

    http://www.InstantSSL.com/SSL-certificate-support/csr_generation/SSL-CER...

    In General, a standard server certificate just because we don't do a lot of fancy with it - just check identity. CN in the CSR must match the FQDN in this case...

  • Clients vpn AnyConnect and cisco using the same certificate

    Can use the same certificate on the ASA client Anyconnect and cisco vpn ikev1-2?

    John.

    The certificate is to identify a user/machine rather than the Protocol, then Yes, generally 'yes' you can use the same certificate for SSL/IKEv1/IKEv2 connections.

    What you need to take care of, it's that said certificate is fulliling Elements of the Protocol, for example implmentations IKEv2 is 'necessary' particular KU are defined and client-server-auth/auth EKU are defined on the certificates.

  • Memory not fully usable in the pool allocation?

    Hello

    We have a few "issues" with Org CDV is deployed under the pool allocation model. It is not possible to use the RAM allocated by 100% (or any value close to 100%). When you try to start the virtual machines, we receive an error for the allocation of resources of the vCenter (lack of resources...). It turns out when you look at the list of resources that 'Used a reservation' is greater than the sum of reservation of the virtual machines that is already running.

    Example of

    Org vDC has 13 GB of RAM allocated with 20% guarantee = list of resources gets 2662 MB of booking

    VM1 is configured with 5 GB RAM = Gets a booking of 1024MB

    VM2 is configured with 6 GB of RAM = Gets a booking of 1229 MB

    Sum of reserves VM = 2253MB

    Customers point of view, it seems that there are always 2 GB available RAM, RP views (calculated) there are still the 409 MB available that are 20% of the 2 GB of RAM. If the client sets up a new virtual machine with 2 GB, tries to start, but it does not work because of insufficient resources.

    When you look at the list of resources in detail, that it's somehow clearly why it fails. The used reserve is 2521 MB, so only 141 MB are available. It is about 700 MB usable for the customer.

    I think it has to do with the charge of the virtual machines, although the General value of resource pools does not explain this difference

    This also occurs when you use other percentages of RAM guaranteed.

    This behavior is - although somewhat understandable - boring.

    To avoid calls to the technical support of customers complain about this issue (in my opinion), there are 2 possibilities

    1. explain the situation/reason for customer and tell them to order more RAM. First of all I don't think that the majority will understand it or worries. And as long as we can't calculate how it takes over is a no go.

    2. Add a buffer to the quantity of RAM. It's what we right now - we add 10%. It works, but customers see that they have more available RAM that they ordered. Integration with billing is too difficult.

    Other vCloud Director users are aware of this issue, too? STI is expected to 'fix' that in future releases? As vCloud Director auto setting RP booking limits somwhow.

    Best regards

    Is it in vCloud 5.1.2 or 5.1.0/5.1.1? If you're on 5.1.2 and using a single cluster for the allocation (inelastic) pools, you can force elastic mode.

  • AnyConnect and SSL - VPN without client

    Hi Daniel

    It's a little complicated if you want a granular authentication and authorization, but it works.

    I'm running an ASA with IPSec, SSL Client and clientless SSL.

    The main challenge is to put in place its own structure of profile cards, connection profiles, group policies and dynamic access policies.

  • ESXi 5.1 - Exchange 2007 - file Page memory and CPU allocation

    I'm currently migrating a class Cluster CSC Exchange 2007 running on vmware on windows 2008, 2003.  It is also a SCC Cluster.  I followed all of the vmware and MS best practices, but not sure of one thing IM is the size of memory and CPU allocation page/swap file.  I have 5 Esxi hosts and each is running only Exchange 2007 comments according to vmware and MS recommendations when you use the Clustering of CSC.

    Each host has 2 CPUs to 6 cores per processor and 48 gb of Ram and that each host will have only a guest, would like to send it to the guest.  I read somewhere that it is recommended this page exchange 2007 memory size + 10 mb file.  Do I really need to get the page to the size of the file?  250 GB of disk space is a lot for swap files! IM also not sure what to set the allocation processor too.  If someone can point me in the right direction, I would be grateful.

    Thank you

    Dave

    Hi dlargeit,

    First of all, off - welcome to the VMTN forums!

    I'm with Josh26 I've ever seen any recommendations indicating that when a CCS cluster virtualization virtual machine by host is taken in charge. It is recommended to keep only a single node SCC by host (which is true for all virtual clusters or technologies like Exchange CSC/CCR/DAG), but there is nothing specific regarding the keep only a single virtual machine by host.

    On the file page, you are actually right on that.  For Exchange 2007, the paging file must be on the amount of memory configured as well as 10 MB to account for overhead costs of the kernel.  It is recommended by Microsoft and it is planned to provide enough space page Exchange should exchange more provide the necessary overhead if meet you a server failure and need to create a complete memory dump.

    You can find this recommendation here: http://technet.microsoft.com/library/aa996719 (EXCHG.80) .aspx

    In terms of CPU allocation, which should really be made according to your individual needs rather than just give all the resources the VM on the ESXi host.  Microsoft lists the maximum recommended for processor resources (Planning Processor Configurations: Exchange 2007 help) and it says that 12 hearts is the maximum for mailbox or Hub Transport box.  Is your really big enough environment need a lot of CPU resources?  Why not start small and increase it if necessary?

    You are in control of your own destiny in some of these configurations.  If you know the recommended page file size is 10 MB of RAM +, do not give the server more RAM is really needed, or you will have to pay for it in the consumed disk space to host the pagefile.  See the guide to memory resources (Planning Memory Configurations: Exchange 2007 help) to understand the maximum rates of memory for Exchange.  You will see that the maximum memory is 32GB, so there are very few reasons to assign all 48GB of RAM on your server, if it can even use.

    In short, the size of the server based on the real needs and I am confident, that you will have a virtualized Exchange system that performs as well as physical.

  • sign the document with 'Draw my signature' and send it via http-post

    Hello

    I have a pdf document with a signature field. When im opening with AcrobatReader XI, I can sign / Place Signature / draw my signature. I can't 'save a copy '. It works pretty well.

    Now, I place a button in the pdf document to be sent via http post to a given address. When I now open this PDF in the XI AcrobatReader, trying to sign. I can only do this with sign / Place Signature / use a certificate. But there is no way to "draw my signature."

    Did I miss an option to do this? Pls tell me if he has a chance to sign the document with 'Draw my signature' and send it via http-post.

    Or is this part of the concept? When I'm looking for a solution, I found EchoSign electronic signature.

    What is available depends on how the as is put in place. If you include a button with an action of type 'Submit form' and/or reader - enable the form, then e-signature (signature of drawing) will not be available in the player. If the document is compatible player then digitally signing will. So for what you want, do not Reader-enable the document and you can use the submitForm JavaScript method to submit. The site that has the JavaScript documentation was not available at the time I wrote this, but post again if you need help with that.
