Cisco VPN :: MAC-Based Authentication In ASA 8.2 AnyConnect VPN
Sep 19, 2010
I have been configuring anyconnect VPN. The requirement from customer is to configure MAC address based authentication for anyconnect clients. I have gone through various cisco documents. I couldnot find this option explained. Is MAC address based authentication possible in anyconnect vpn without having AAA server in place?There is an option to select end point attribute as MAC address, while creating Dynamic access policies. But at the host scan configuration of Cisco secure desktop, there are no options for performing MAC retrieval.
My ASA is running on version 8.2(1) and ASDM version 6.3(1) and a memory of 512 MB RAM. Any way for MAC based authentication in cisco anyconnect VPN.
I activated the following Cisco AnyConnect License on my Cisco ASA 5510 running the software version 8.3(2):webvpn has been configured on my ASA, but everytime I try to connect from a Window system (xp, 7 or 8), the process always stops at the menu "Download" (as seen on the image below). My goal is to connect via web-based without doing any manual installation of the Cisco AnyConnect VPN Client on my system.
I have two sets of local users who access internal networks vai the Anyconnect application on a Cisco ASA 5505.One user needs to access 1 ip address while about 7 users access abotu 4 addresses.
I have a group called xyz1 which currently has the one user in the connection profile. I guess to reaffirm my thought, If I create another connection entry called xyz2, can I assign the other 7 or 8 users to it?
If I can do this, how can I ensure that each connection entry only has access to specific IP addresses on the internal network?
I have an ASA running 8.2.x code with AnyConnect 2.4.x.I have both Radius and LDAP (AD) AAA available.If a user connects from a company owned laptop, I want to push down AnyConnect client ProfileA (with scripts to map drives etc...) and network ACL's set A.
If a user connects from any other computer, I want to push down AnyConnect client ProfileB (no scripts etc...) and network ACL's set B.
What I would like to do is CSD to do a machine certificate check (for presence of a cert from my private CA) and to assign a EndPoint Policy attribute (Managed on successful check or Unmanaged on failure). I can then use DAP to tailor the ACL's that get set.
It seems like the only way to handle AnyConnect client profiles is with Group-Policy. Using LDAP I can assign a user to a Group-Policy, but I have no way of determining is they are coming in from a company laptop or not when assigning the Group-Policy. DAP can not assign an AnyConnect client profile.
If at all possible, I do not users to have to pick a conenction profile or use different URL's.
I currently have a asa 5500. is there a way to authenticate based on mac address throught the vpn client. We are haveing problems with useres using there home computers to connect. Yes they are smart enought to install the client and copy the profile.
We use a combination of Cisco ACS and Cisco catalyst 3560 switches for network authentication and authorization. Clients (Windows XP) have a certificate installed which will grand access to the network and put them in the correct VLAN. So far, so good. Some users are testing with Windows 7 in the same set-up as above and run into strange behaviour. The problem is that after a random timer the machine gets de-authenticated and nothing besides a reboot works to get the computer authenticated again (from a Windows point of view). It looks like this only happens to users who are using a certificate to authenticate, Windows 7 MAC bypass users have no such problems. If it occurs, the following logging appears in ACS: [code] We are using ACS 4.2(0) Build 124 and 3560-48PS switches with IOS 12.2(55).
I have a query regarding MAC authentication for end systems on ASA 5520. Inspite of proving MAC address in endpoint authentication along with AAA, only AAA attribute policies are getting created. MAC authentication is not happening.
Is there any requirement like LDAP or AD is required for MAC authentication?
I am doing a proof of concept with anyconnect and certificate authentication. with 3.0 i was able to do this with a certificate from my CA and a client cert in a smartcard. I have upgraded to 3.1 and now it doesnt work anymore ( i need 3.1 and Asa 9.0 because of IPv6 Split-tunneling).Reading the forum i got some info that the ASA cert must have a EKU value of 'Server Authentication' and the client cert must have a similar EKU (client Auth)
I have cisco 2504 WLAN controller with 7.4 IOS. My query is can I configure the MAC authentication with certificate based. And without using any external servers like Radius, ACS and LDAP.
I would like to configure RADIUS authentication and authorization in ASA 8.2 (ADSM 6.2) by configuring Cisco anyconnect VPN client connection profile.So the end result would be user enters his username, password and a token in any connect client, then the RADIUS server validates this information and sends the user attributes to ASA upon successful authentication.I would be grateful if i can get the step by step procedure to achieve this:The below is what iam trying to do:
1) Create an AAA server group. 2) Add the AAA server to this group (here its RADIUS). 3) create an LDAP-cisco ASA group mapping (for authorization) 3) Add a group policy and create IP pool. (We can add two types of group policies, one is internal and external. Not sure which one to select here). 4) create a any connect vpn client connection profile. Here we specify the created server group name, IP pool and group policy.(While creating a connection profile, it asks us to select an interface. As of now i have only one interface which is "inside". Not sure what the interface "outside" means).
I have configured an Asa 5510 as SSL vpn gataway ver 8.2(4) Anyconnect Essential. The clients are authenticated via Radius and OTP password.All work well since yesterday. When I have did same configuration changes. My objective was has that the clients accept the self signed certificate issued by the Asa whitout give the warning about the private cert.
So I have try to generaste a new certificate with FQDN equal to myasa.mydomain.com and also a CN=myasa
Then I have change the profile XML file of my anyconnect in this way: [code]
Recently we updated to the Anyconnect 3.0 client. I see the new 3.1 client is out and we are currently testing it for production. My question though is since updating to 3.0 our end users receive a message at the bottom of their client stating "No valid certificates available for authentication" They can still VPN in since we dont do certificate based authentication but we have been getting tons of questions on this. I would like to stop these messages from appearing and I am not sure if its just how the new client behaves or if its something configured on our ASA's.
I have an ASA 5520 and I am having trouble getting the AnyConnect VPN authentication timeout feature to work properly. I thought I did have it working a couple of months ago, but right now it is not giving me more than the default 12 seconds. I have tried intervals of anywhere from 25 seconds up to 120. I am currently runnign version 6.4 on the ASA and AnyConnect 2.5.3055.
I can't seem to find any documentation to how to get this working. I'm trying to make it so that only users of a certain AD group are authenticated for my Anyconnect VPN on my ASA 8.2.2
I've found the documentation on how to prevent logins using the msNPAllowDialin attribute, but not how to base it on group membership (memberOf) [code] I need to do any kind of restrictions inside the actual group-policy TESTGROUP ?
I am deploying ISE with WLC 7.4. I have two SSID(s) running in my network 1. Corporate & 2. Services. I have a domain setup lets say "AD.com" with 4 groups 1. Corporate, 2. Services, 3. Employees, 4. Contractors.Here is an example of the scenario that I want:
AD.com Group : Corporate's User : 1. C_USER1 2. C_USER2 3. C_USER3 4. C_USER4 5. C_USER5
[code]....
Now what I want to do is have 802.1x authentication on my Corporate SSID that will check in AD.com, ONLY AND in ONLY corporate group for authentication. That is only C_USER1 to C_USER5 are allowed to connect to it. Users from any other AD group shouldnt be authenticated on this SSID.The same for the services group & SSID.
I've been working on trying to get RADUIS authentication working for devices connecting to our corporate mobile APN. Out APN provider sends us Username & Password attributes which I can authenticate fine using ACS 5.2 but I'm having a problem using other attributes sent in the Access-Request. We have mobile SIM cards with an MSISDN value match with a physical device with an IMEI value. The SIM cards cannot be used in other devices, only their matched device. The provider passes us the MSISDN attribute under RADIUS-IETF 31 and the IMEI under a VSA of 3GPP-IMEI
What is the best way of being able to authenticate a user and match the MSISDN and IMEI associated to that user?
I have a need to utilize two factor authentication using a machine certificate and users AD crednetials. What we would like to do is to have the ASA and AnyConnect verify the certificate exists, check against our in house CA for validity, if valid pass the user credentials to the AD servers and establish the tunnel. If not valid quarantine the session and pop a message to the user to contact the help desk ASAP. My guess is the following (using ASDM 6.6, ASA 8.6.1, ASA 5545-X):
1. under the connection profile I have select BOTH for authentication and added a AAA server group.
2. under Cert Management I have added the 3 certs that are present on all company mobile assets
- Cert America - Cert Europe - Cert Root
3. I have an identity cert installed from the company CA and it is selected as the device cert under connection profiles
4.Local Cert Authority is Disabled
5.Under Remote Access>Advanced>Certs for AnyConnect>
- I have mapped DefaultCertifiateMap pri 10 to Company_Cert connection profile
- The mapping is looking for Subject: CN: <Contains> (string) ----where string is a common component of each Cert listed in #2.
Question #1 - Is this correct for utilizing certs and AD auth or have a missed any steps?
Users are directed to a an initial installation URL - where the AnyConnect client performs the installation and passes down the intial AC profile which auths using only AD creds. On subsequent connections users who pass the certificate mapping check are migrated to the connection profile which uses the dual authentication method.
Question #2 - When I attempt a new installation of AnyConnect using the two factor URL . I receive an error "certificate validation error" and the installation fails - for the life of me I can not figure out why???? The machine has all three certs, using IE9 as the browser.
I want to connect with AnyConnect Secure Mobility Client 3.0.2052 to ASA 5540 Version 8.4 and SSL Premium License.The clients using Maschine Certificate to authenticate to ASA. This works fine.Now I want to setup a DAP to verifiy the client against the Microsoft AD using LDAP. I configured LDAP server in ASA see:aaa-server LDAP protocol ldap aaa-server LDAP (inside) host ldap.com ldap-base-dn DC=x,DC=x,DC=x,DC=com ldap-scope subtree ldap-login-password ***** ldap-login-dn ***** server-type microsoft ,I can see that it works if I test the server via the testbotton in ASDM and I see it in CLI "debug ldap 255" also. But if I configure in DAP: AAA Attribute ID:memberOf = DomainMember I can not see any request to the LDAP server during I try to connect with the Client und the DAP doesn't match.
I'm trying to set up vpn with ASA 8.2(5) and Anyconnect 3.0.4235. The goal is to force user to connect from registered machines only (winXP & win7 x32 and x64). To do this, I used machine certificates issued by own CA. Certificate is installed in machine store. I use double authentication (aaa & certificates). Everything works fine, AnyConnect browses cert store, ASA validating machine certificate, then user is prompted for username/password and finally if all is correct - connection is established.My problem is, that for new installation (new host), AnyConnect fails at first connection attempt. If I use aaa authentication only, connection is established, but if I use aaa & certificates - connection fails. The appropriate .xml profile is predeployed at client host asa well as machine and root certificates.Important: When first try (aaa auth) succeded, others are always OK (with aaa. certificate or aaa & certificate authentication). Only the first one fails.The goal is to succesfuly establish connection with aaa & cert.
With DART i get: ****************************************** Type : Error Source : acvpnagent Description : Function: CTransportWinHttp::WinHttpCallback File: .CTransportWinHttp.cpp Line: 2150
[code]....
Certificate is valid for sure, and as I mentioned before, if first use aaa only, the second try is OK. At ASA with debug crypto ca 255 can't see any certificate from client.
Any instructions to configure an ASA to allow authentication by certificate only on an AnyConnect vpn?I'm running an ASA 5505 with 8.4(1) and AnyConnect 2.4.7030 on an Android phone.I currently have the AnyConnect client connecting ok using username / password for authentication.
I have loaded the company root certificate (internally generated) into the ASA "CA Certificates" and generated an Identity Certificate for the ASA.
want to connect with AnyConnect Secure Mobility Client 3.0.2052 to ASA 5540 Version 8.4 and SSL Premium License.The clients using Maschine Certificate to authenticate to ASA. This works fine.
Now I want to setup a DAP to verifiy the client against the Microsoft AD using LDAP. I configured LDAP server in ASA see: [code]I can see that it works if I test the server via the testbotton in ASDM and I see it in CLI "debug ldap 255" also. But if I configure in DAP: AAA Attribute ID:memberOf = Domain Member I can not see any request to the LDAP server during I try to connect with the Client und the DAP doesn't match.
I'm trying to find out the options for authenticating remote users via IMEI and MISDN values via ACS 5.3/I'm unfamiliar with the Radius attribute options here and what kind of request/response we can utilise. Also previously I could define IP pools on ACS 4 but can't seem to do that now. Is there a way have ACS 5.3 to provide a DHCP server address for the connection ?
Looking to fine tune Cisco IPSec client RA-VPN authentication on our ASA-5510. Currently using NT Domain authentication. It's been working fine for quite a while but is too broad a brush. It authenticates anyone who is in the domain. We need to only authenticate folks who are in a specific AD remote access security group. I'm testing LDAP but am getting the same results. I can get it to authenticate based on overall domain membership but can't seem to figure out how to check group membership.
We've updated to ASA 8.2(1) and ASDM 6.2(1). It seems to have more LDAP functionality but I'm not an LDAP expert. I've posted an image of the LDAP server dialog from the ASDM. I originally tried putting the Group DN in the Base DN field but kept getting a "can't find user" error when testing. I also tried adding the group info in the "LDAP parameters for group search" field at the bottom. But it doesn't seem to be looking there. Note that the current value is the Group Base DN only. I also tried putting "memberOf=" in front of that. Still no luck. The values shown in the image work for simple domain membership.
I have been successfully able to setup Cisco AnyConnect VPN on ASA 5520 with 8.4 code. I have set it to authenticate against the RADIUS Server (Microsoft Windows 2008 NPS server). I have noticed one thing, on the server under "Constraints and Authentication Method". I picked MS-CHAP-v2, but it is considered Less secure authentication methods. I can click on Add and choose other Authentication methods like Smart Card or other Certificate, PEAP, EAP-MSCHAP v2. I picked PEAP but then the VPN does not work.
So first of all does it really matter if I just leave it to MS-CHAP-v2? Because from my understanding is that AnyConnect will authenticate to ASA and then ASA in the backend talks to the RADIUS server so from a security stand point this scenario shouldn't it be sufficient as no un encrypted or less secure information is available to the outside world? Secondly is there any documentation on using PEAP with Cisco AnyConnect?
I want to configure IEEE 802.1x port-based authentication on cisco switches, preferable 2960 series. Which models support this feature?. I have try with some older switches but it doesn't works properly on everyone. I have upgraded them whitout better results, there is namely an issue with TLS handshaking on some switches which produces authentication to fail.
i am planning to buy 867vae router and i would like to ask you a few things the configuration is through cli only(because i am not familiar with cli) or it can be web based ? the basic configuration for dsl and routing are preconfigured or i have to do everything from scratchf? if someome has configured let say a draytek router, is it the same with this router or its a different world?
I am having a problem trying to get to my root view. I am trying to set up some views to allow restricted access to one of our routers.I am running C2800NM-ADVIPSERVICESK9-M Version 12.4(20)T as the IOS and have the following AAA entries in my config
How can I configure police-based nat to allow ICMP-only traffic on asaos 8.4.1 or 8.3?On 8.3 it was very simple:global (outside) 1 interface ,access-list outside_nat_outbound extended permit icmp any any,nat (outside) 1 access-list outside_nat_outbound.
