Cisco VPN client + Cisco router + MSW CA + certificates

Dear sirs,
Allow me to approach you about the following problem.

I wanted to use a secure connection between Cisco VPN client
(Windows XP) and Cisco 2821 with certificate authentication.
I used Microsoft certificate authority (Windows 2003 server).
Cisco VPN client used eTokenPRO Aladdin as a certificate store.

Enrollment certificate to MSW CA and its placing into eToken ran O.K.
Cisco VPN client hasn't problem with eToken cooperation.
Enrollment certificate from Cisco2821 to MSW CA ran O.K. too.

Cisco 2821 configuration is standard. IOS version 12.4(6).

Connection attempt from Cisco VPN client to Cisco 2821 was
terminated with error messages:

ISAKMP:(1020):Unable to get router cert or routerdoes not have a cert: needed to find DN!
ISAKMP:(1020):SA is doing RSA signature authentication plus XAUTH using id type ID_FQDN
ISAKMP (1020): ID payload
        next-payload : 6
        type         : 2
        FQDN name    : cisco-ca.firm.com
        protocol     : 17
        port         : 500
        length       : 25
ISAKMP:(1020):Total payload length: 25
ISAKMP (1020): no cert chain to send to peer
ISAKMP (1020): peer did not specify issuer and no suitable profile found
ISAKMP (1020): FSM action returned error: 2
ISAKMP:(1020):Input = IKE_MESG_INTERNAL, IKE_PROCESS_COMPLETE
ISAKMP:(1020):Old State = IKE_R_MM5  New State = IKE_P1_COMPLETE

Are there some refence where is possible to find some information about
this problem? Exists somebody who knows how figure it out these errors?
Thank you very much for your help.

Best regards
P.Sonenberk

Re: Cisco VPN client + Cisco router + MSW CA + certificates

Hey guys, It is odd that the router is not finding the cert after the IKE matches the cert and validates it, I this certainly is not right, however I would go ahead and configure certificate mapping on this router to force the client to be matched to a specific IKE group, for that matter you will need to change your config a little bit to use iskamp profiles:

Re: Cisco VPN client + Cisco router + MSW CA + certificates

Please change isakmp policy command "authentication rsa-encr" to "authentication rsa-sig" and try it again.

Re: Cisco VPN client + Cisco router + MSW CA + certificates

Good morning,

thank you very much for your advice, time and your interest.

But I've got these raws in the cisco router configuration:

crypto isakmp policy 10

encr 3des

hash md5

authentication pre-share

group 2

!

crypto isakmp policy 20

encr 3des

hash md5

group 2

!

crypto isakmp policy 30

encr 3des

hash md5

authentication rsa-encr

group 2

crypto isakmp identity hostname

!

crypto isakmp client configuration group Group159

key Key159Key

pool SDM_POOL_1

acl 100

!

crypto isakmp client configuration group it

domain firm.com

pool SDM_POOL_1

acl 100

!

crypto ipsec transform-set 3DES-MD5 esp-3des esp-md5-hmac

!

crypto dynamic-map SDM_DYNMAP_1 1

set transform-set 3DES-MD5

reverse-route

!

crypto map SDM_CMAP_1 client authentication list sdm_vpn_xauth_ml_1

crypto map SDM_CMAP_1 isakmp authorization list sdm_vpn_group_ml_1

crypto map SDM_CMAP_1 client configuration address respond

crypto map SDM_CMAP_1 65535 ipsec-isakmp dynamic SDM_DYNMAP_1

The group of the policy number 20 has "authentication rsa-sig" implicit on.

I'm afraid the problem is elsewhere or I don't understand your advice.

Thank you for your cooperate, have a nice rest of this day.

Re: Cisco VPN client + Cisco router + MSW CA + certificates

Well, in your first post, you did not include the other isakmp policy, I though isakmp policy 30 is the only one.

You'd better to provide the debug output for us to help.

debug crypto isa

debug crypto ipsec

debug crypto pki (there are some options follow)

Re: Cisco VPN client + Cisco router + MSW CA + certificates

Good morning,
I'm terribly sorry. Yes, there wasn't full cisco configuration in my  first question.
I'm glad you want to find a solution.

Well, I've used these debug command:

debug crypto pki messages, debug crypto pki transaction, debug crypto  isakmp,
debug crypto ipsec

And there are two devices:
Cisco 2821 IP address is 10.1.1.220, cisco-ca.firm.com.
Personal computer MSW XP client VPN IP address is 10.1.1.133,  cisco-vpn1.firm.com,

Re: Cisco VPN client + Cisco router + MSW CA + certificates

Based on debug output, I think the problem shoult be here:

Jan 22 08:19:00.528: ISAKMP:(1001): peer wants a CT_X509_SIGNATURE cert
Jan 22 08:19:00.528: ISAKMP:(1001): issuer not specified in cert request
Jan 22 08:19:00.528: ISAKMP:(1001): No issuer name in cert request.

When client sends Cert request, it don't tell the issuer.

Are you using Cisco VPN client, if yes, please check log to see if you could find any error such as "not find root cert".

Re: Cisco VPN client + Cisco router + MSW CA + certificates

Good morning,
thank you for your advice.

I've used VPN Cisco client ver.4.6.02.0011 and WXP PC.

Yes, this raws of the log are suspicious, it's the truth:

Jan 22 08:19:00.528: ISAKMP:(1001): issuer not specified in cert request
Jan 22 08:19:00.528: ISAKMP:(1001): No issuer name in cert request.

But this ISAKM step ended with this messages:

Jan 22 08:19:00.532: ISAKMP:(1001):SA authentication status:
       authenticated
Jan 22 08:19:00.532: ISAKMP:(1001):SA has been authenticated with 10.1.1.133
Jan 22 08:19:00.532: ISAKMP:(1001):SA authentication status:
       authenticated

and I can see in Cisco router:

cisco-ca#sh crypto isakmp sa
IPv4 Crypto ISAKMP SA
dst             src             state          conn-id status
10.1.1.220      10.1.1.133      MM_KEY_EXCH       1002 ACTIVE

It's suspicious too.

Re: Cisco VPN client + Cisco router + MSW CA + certificates

Client did send its cert and the router also validated it successfully.

The problem is that router did not send its cert to client since there is no issuer specified in client's cert request.

http://cdetsweb-prd.cisco.com/apps/goto?identifier=CSCsc08040You can try a vpn client with fix of bug CSCsc08040 to see if it make any difference.

Per my understanding, Cisco VPN cliend should specified the issuer in its cert request. But other vendor's client might not do that.

Addmittedly, from router point of view, the router should still send a cert to client by using its existing cert even if there is no issuer specified in client's cert request. (There was a bug about this behavior and it should be fixed in your IOS version 12.4(6)). So, regarding to the configuration, I believe that you can try to configure "isakmp profile" (you can specify trustpoint in profile, you might need to configure a map as well, sorry I don't remember exactly syntax ).

The third thing is a bug on router side.

CSCsu84414

this bug is not a exactly match but it might be related. It won't hurt to try a IOS version with the fix of this bug.

Re: Cisco VPN client + Cisco router + MSW CA + certificates

Good morning,
it seems to be a little complicated.........
Well, client certiface has information about "issuer" in.
Report of our client certificate is here:

Certificate data
Serial number    61 3c 42 d1 00 01 00 00 00 0f
Issued to    cisco-vpn1
Issued by    firm-cu

Private key Data:
Key Size    1024 bits
Container name    5b1caef5......
Modulus        b0 be 93 7c ............
Key specification    AT-KEYEXHCANGE

I don't know why there is this error messages in Cisco router logs:

Jan 22 08:19:00.528: ISAKMP:(1001): issuer not specified in cert request
Jan 22 08:19:00.528: ISAKMP:(1001): No issuer name in cert request.

I'm sorry, but this URL: http://cdetsweb-prd.cisco.com/apps/goto?identifier=CSCsc08040 is
unavailable - time out for connection ............

>>Addmittedly, from router point of view, the router should still send a cert to client by using its existing cert even if there is no issuer specified in client's cert request.

I agree with you, but there is this error messages in Cisco router logs:

Fine, isakmp configuration, there could be some mistake......
Does somebody know what mistake? Does anyone have a solution to fix this problem?

Thank you for your cooperation.

Re: Cisco VPN client + Cisco router + MSW CA + certificates

Hey guys, It is odd that the router is not finding the cert after the IKE matches the cert and validates it, I this certainly is not right, however I would go ahead and configure certificate mapping on this router to force the client to be matched to a specific IKE group, for that matter you will need to change your config a little bit to use iskamp profiles:

Dear Mr. Martinon,

GREAT! "Certificate to ISAKMP Profile Mapping" is solution.

I added this raws to Cisco router configuration:

!
crypto pki certificate map cert_map 10
subject-name co ou=it
!

and raws

!
crypto isakmp profile certpro
  ca trust-point firm-cu
  match certificate cert_map
!

And now is authentication between Cisco VPN client and Cisco 2821 all right.
Cisco VPN client is working well.
(Note: Cisco VPN client has its certificate in eToken PRO Aladdin.)

It's a pity and a little confusing that Cisco configuration examples hasn't notice
about this problem ................

Well, there are still some strange messages in logs, but it's for some
"Cisco guru". For example:

*Feb  2 09:55:19.388: ISAKMP (1002): processing a CT_PKCS7_WRAPPED_X509 cert
*Feb  2 09:55:19.388: ../cert-c/source/certobj.c(853) : E_INPUT_DATA : invalid encoding format for input data
*Feb  2 09:55:19.388: CRYPTO_PKI: status = 0x705(E_INPUT_DATA : invalid encoding format for input data): BER/DER decoding of certificate has failed

*Feb  2 09:55:19.452: ISAKMP:(1002): peer wants a CT_X509_SIGNATURE cert
*Feb  2 09:55:19.452: ISAKMP:(1002): issuer not specified in cert request
*Feb  2 09:55:19.452: ISAKMP:(1002): No issuer name in cert request.
*Feb  2 09:55:19.452: CRYPTO_PKI: Trust-Point firm-cu picked up
etc.

For hardworking readers the main part of the Cisco router logs are below.

Mr. Martinon, thank you for you help and your time.
Thank you for your cooperation.
Have a nice day.

Re: Cisco VPN client + Cisco router + MSW CA + certificates

Hi Peter,

I am glad this worked for you, does this mean that your client connects fine already? Logs show something else..

Re: Cisco VPN client + Cisco router + MSW CA + certificates

Hi Ivan,

>Logs show something else..
What do you mean?

Cisco VPN client got IP address form Cisco router and connection was
opened. I can see IP address (192.168.200.1) from Cisco in WXP (PC with VPN client) route table
and I can do login to Cisco router as its user. Cisco VPN client displays "a shut lock".
By the way there is log from Cisco VPN client (main part) below.
Cisco has IP address 10.1.1.220, client has IP address 10.1.1.133.

Important raws are:

Re: Cisco VPN client + Cisco router + MSW CA + certificates

Oh, OK, great to hear, I was concerned by the following message:

*Feb  2 09:55:35.540: ISAKMP:(1002):deleting node 1502050166 error FALSE reason "Done with xauth request/reply exchange"

But if it is all good then glad it works now.

Hi Ivan,

>Please rate useful posts.

Well, but I don't know how to do it.

I can't find any instructions.


Have a nice day.

Re: Cisco VPN client + Cisco router + MSW CA + certificates

Hi Ivan,

I wanted to put four stars, but that HTML is out of order.

It seems there is some problem with java, I don't know.

Could you tell it your webmaster?

You've got FOUR YELLOW STARS for your advice and help.

Thank you, have a nice day.
P.Sonenberk


P.S. Why there are green stars there?
