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.
View 8 RepliesI 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 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?
We have an ASA 5510 that handles our vpn client traffic, and occasionally, we run into a client that, while using Cisco AnyConnect in conjunction with Phonefactor, the connection attempt will timeout before the connection actually establishes.The odd thing is - The logs show the client finished connecting, and the Phonefactor server shows completed authentication. We even added a custom timeout script to increase the default 12 second timeout to 30 seconds.This behavior has proven difficult to find a common factor for, as it has affected different versions of the client, 2.3 and 2.5, as well as Windows XP, Vista and 7 installs. This problem does not affect our Anyconnect/RSA clients, and if the same person on the same client with the issue is migrated over to the Cisco IPSec vpn, the problem disappears.

All of them were entered manually on the ACS server and are configured to authenticate using TACACS+. Some of the devices can authenticate ok, but other will timeout. I did a tcpdump on the firewall port and can see the device sending the SYN to the ACS server but the server sends no reply to the device.

*previously*! i was able to auto connect fine on this home network via wifi.the line and box recently changed, same provider, and now i'm the only one who can't connect.the SSID changed, but i've done all the usual routines, deleting and re-adding manually, etc. but nothing so far...
i *don't* think this is a case of changing gear, but i don't know enough about internet/connection/configuration to fix this. yet!
NB: when i perform the reset on the box as instructed, using the provider's setup software - i am not the account holder - for the wifi, it shows connected very briefly in the animation, and then goes off again; this is the authentification/verification failing, i conclude.
so: with what is said above, i'm wondering if my antivir is to blame, or the windows firewall settings.or malwarebytes.i'm going to study the info i've got off my system, and looking at the router via the http routine, offline, as i now have to get off the internet(...); i'll get the infos together so i can post something useful.

View 5 Replies View RelatedI am using ISE 1.1.3.124.My first question:I want to know the relation between the attribute "WasMachineAuthenticated" and the MAR (MAchine access restriction in advanced setting for AD).Is-it the same or not ?Once you time out, you need to do machine auth again. What is the timer ?Using the attribute "WasMachineAuthenticated", is-it the same timer that you configure in MAR ? In a distributed environnement, is the information about machine previously authenticated replicated to all policy node ?Because, if a swicth has 2 radius-server, we are not sure that it will point everytime to the same server.

supplicant - W7 with cert
authenticator - Catalyst 2960 with IOS 15.0(1)SE2 /newest/
authentication server 2x - W2008/NPS like a RADIUS server
The problem is the end station that are still connected to the supplicant port /use a EAP-TLS/ after the reboot supplicant! All of them will be put into the Guest VLAN instead of static VLAN 34!
[The question]
What is wrong and how to configure/tune and what authenticator or authentication server to prevent after the reboot to observe a authentication timeouts? Of course the supplicant after 20 minutes /next EAPOL start farmet put into VLAN 34.

I have inherited the support of an ASA5520 running 8.0(3)12 code and I believe I have a pretty simple question here that I haven't been able to figure out on my own. I have a few users that connect to the box via IPSEC VPN client connections. They want to be able to leave up a RDP based connection, for monitoring purposes, for a most of the day, but thier RDP connection keeps getting discounnted after a few hours. The VPN connection never gets disconnected, just the RDP session running through it. I have another box running 8.0(4) code and they can leave up the RDP sessions as long as they like without getting disconnected from the server(s). I have compared the configs of both boxes and don't see any glsring differences in regards to the configuration that would cuase the RDP sessions to either to stay up or be disconnected after an inactivity type scenario.
What to look for in regards to identifying the timer that is disconnecting the RDP session after a period of time.
I configured multiple vlan on my Cisco ASA5520. Everything work perfectly except RDP (3389) connections. The connections are established but but after a period of inactivity, the user is disconnected from server (black screen). The same problem happens with other type of connections (client/server), exemple : Oracle, file sharing. Before installing the ASA, computers and servers were in the same vlan and it worked well.
There's a notion of inter vlan timeout connection ?
When users are VPN connected their telnet sessions timeout after an hour of inactivity. Looking at the connections on the firewall they are showing as idle. Is there a configuration change or something else that has to be modified?

View 1 Replies View RelatedI 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.

But at the host scan configuration of Cisco secure desktop, there are no options for performing MAC retrieval.

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)
View 4 Replies View RelatedI 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.

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 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.

View 2 Replies View RelatedI'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.
