Anyconnect client issue

Is there any reason that the connection settings don't save in the anyconnect client? When the users first connect to the website to get the anyconnect client they are fine. Also if they reconnect by going to the website they are fine. But if they just try to connect through the client itself (without going to the website) they have to retype the connection name. Is there a way to fix this? Any help would be appreciated. Thank you!

WebLaunch mode-Lets the user enter the URL of the security appliance in the Address or Location field of a browser using the https protocol. The user then enters the username and password information on a Logon screen and selects the group and clicks submit. If you have specified a banner, that information appears, and the user acknowledges the banner by clicking Continue.

Anyconnect CLIENT configuration issues

Hi all,
OK, Does anybody know of any documentation or has any knowledge on how to configure the AnyConnect CLIENT so that I can change the authentication method from RSA to RADIUS.
Now, I can do all of the work required on the ASA, and this is where everything goes south.
Example:-
AC client connects to ASA - profile says use RSA - user get prompted for username / passcode. - so far so good.
Change ASA to use RADIUS from RSA - save config.
AC Client connects to ASA - Nothing - as Client is configured to use RSA BUT ASA is listening for a RADIUS request - as this can be seen in the logging.
Anyone any ideas as to where I'm going wrong.
Further to this, I have tried to create a blank xml profile, trawled the forums (as best I can) but not seen anything that gives me the answer.
Stephen

Hi Stephen,
After changing the authentication to Radius server , I hope you have changed the connection profile to use the correct authentication server.
Please share the relevant configuration from ASA including connection profile and group-policy that the user connects and the AAA server configuration on ASA.
Regards,
Dinesh Moudgil
P.S Please rate helpful posts.

Cisco AnyConnect VPN won't install, says There is a newer version of the AnyConnect client already installed

I had an issue with my Cisco Anyconnect VPN not working, so uninstalled it. I've tried a new install and now I get the message "There is a newer version of the AnyConnect client installed" and it won't tell me install it at all. I've gone through various recommendations on the site included this :-
Go to "Regedit" and search for "Deterministic Networks" and delete it.
HKEY_LOCAL_MACHINE \SOFTWARE\Deterministic Networks
Search with the following keywords in the registry, under "Uninstall" or "Components" folders and delete any related entries.

But I've still got the same problem, and just cant find anything to help !

Disable Internet Connection Sharing (ICS) and then try You can disable ICS in two ways:
Per Adapter:
Click the Start button.
Click on Control Panel.
Click on View Network Status and Tasks
Click on Change adapter settings
Right-click the shared connection and choose Properties
Click the Sharing tab
Clear the Allow other network users to connect through this computer's Internet connection checkbox
Click OK
System Wide:

You can now try reinstalling the WiscVPN client again

AnyConnect error " User not authorized for AnyConnect Client access, contact your administrator"

Hi everyone,
it's probably just me but I have tried real hard to get a simple AnyConnect setup working in a lab environment on my ASA 5505 at home, without luck. When I connect with the AnyConnect client I get the error message "User not authorized for AnyConnect Client access, contact your administrator". I have searched for this error and tried some of the few solutions out there, but to no avail. I also updated the ASA from 8.4.4(1) to 9.1(1) and ASDM from 6.4(9) to 7.1(1) but still the same problem. The setup of the ASA is straight forward, directly connected to the Internet with a 10.0.1.0 / 24 subnet on the inside and an address pool of 10.0.2.0 / 24 to assign to the VPN clients. Please note that due to ISP restrictions, I'm using port 44455 instead of 443. I had AnyConnect working with the SSL portal, but IKEv2 IPsec is giving me a headache. I have stripped down certificate authentication which I had running before just to eliminate this as a potential cause of the issue. When running debugging, I do not get any error messages - the handshake completes successfully and the local authentication works fine as well.
Please find the current config and debugging output below. I appreciate any pointers as to what might be wrong here.

Windows 8.1 Preview not working with AnyConnect Client

I had Windows 8 and was running Cisco AnyConnect client 3.0.10055 perfectly.
I upgraded to the Windows 8.1 preview and it tries to download update and then it fails and disconnects with the following message:
An unknown termination error occurred in the client.
Tried uninstalling and reinstalling the client, no luck.
Any ideas?
Thanks,
Eric

I had the same issue with windows 8.1 x64. I believe there is an issue with the windows 8.1 update process where it fails to update some of the drivers properly. I have noticed this issue with other windows drivers after the update. Follow the steps below and you VPN should work again.
1. Uninstall Cisco Anyconnect client.
2. Go to Device Manager and Disable Cisco AnyConnect VPN Virtual Miniport Adapter for Windows x64
3. Go to C:\Windows\System32 and rename vpnva64.sys to vpnva64_Old.sys.
4. Reinstall Cisco Anyconnect client.
5. Go to Device Manager, you see duplicated Cisco AnyConnect VPN Virtual Adapters. Uninstall one of them but do not check the option to remove the driver.
6. Apply the registry fix in this blog: http://www.tomontech.com/2012/03/pro-tip-cisco-anyconnect-vpn-client-and-windows-8-consumer-preview/
7. Try to connect again and your Cisco VPN should work.

Assigning AnyConnect Client Profiles based on the machine?

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.
Is there anyway to accomplish this?

Hi
Did you ever resolve this issue? I am trying to assign a specific IP address based on the hostname or machine cert but the certificate matching doesn't seem to look at the machine cert.
Has anyone got any idea how I could do this?
thanks
Steve

Hello Michael,
The problem here is because we cannot succesfully establish a DTLS tunnel. This could happen because:
- DTLS is blocked somewhere in the path
- A non-default DTLS port is being used
If DTLS is blocked in the middle the issue is because as of ASA Release 9.x and AnyConnect Release 3.x, an optimization has been introduced in the form of distinct Maximum Transition Units (MTUs) that are negotiated for TLS/DTLS between the client/ASA. Previously, the client derived a rough estimate MTU which covered both TLS/DTLS and was obviously less than optimal. Now, the ASA computes the encapsulation overhead for both TLS/DTLS and derives the MTU values accordingly.
As long as DTLS is enabled, the client applies the DTLS MTU (in this case 1418) on the VPN adapter (which is enabled before the DTLS tunnel is established and is needed for routes/filters enforcement), to ensure optimum performance. If the DTLS tunnel cannot be established or it is dropped at some point, the client fails over to TLS and adjusts the MTU on the virtual adapter (VA) to the TLS MTU value (this requires a session level reconnect).
In order to eliminate this visible transition of DTLS > TLS, you can configure a separate tunnel group for TLS only access for users that have trouble with the establishment of the DTLS tunnel (such as due to firewall restrictions).
1. The best option is to set the AnyConnect MTU value to be lower than the TLS MTU, which is then negotiated.
group-policy ac_users_group attributes
webvpn
anyconnect mtu 1300
This makes TLS and DTLS MTU values equal. Reconnections are not seen in this case.
2. The second option is to allow fragmentation.
group-policy ac_users_group attributes
webvpn
anyconnect ssl df-bit-ignore enable
With fragmentation, large packets (whose size exceeds the MTU value) can be fragmented and sent through the TLS tunnel.
3. The third option is to set the Maximum Segment Size (MSS) to 1460 as follows:
sysopt conn tcpmss 1460
In this case, the TLS MTU will be 1427 (RC4/SHA1) which is larger than the DTLS MTU 1418 (AES/SHA1/LZS). This should resolve the issue with TCP from the ASA to the AnyConnect client (thanks to MSS), but large UDP traffic from the ASA to the AnyConnect client might suffer from this as it will be dropped by the AnyConnect client due to the lower AnyConnect client MTU 1418. If sysopt conn tcpmss is modified, it might affect other features such as LAN-to-LAN (L2L) IPSec VPN tunnels.
If DTLS is not blocked in the middle another potential cause for the DTLS failure that DTLS is configured on a non-default port after the WebVPN is enabled (for example, when the webvpn enable outside command is entered). This is due to Cisco bug ID CSCuh61321 and has been seen in Release 9.x where the ASA pushes the non-default port to the client, but continues to listen to the default port. Consequently, the DTLS is not built and AnyConnect reconnects.
The workaround for this problem is:
Disable the WebVPN.
Enter the DTLS port.
Enable the WebVPN.

Unable to use proxy server with MAC OS X Anyconnect client

Hi All,
I have a VPN setup thru a Cisco 5520, Windows clients connect just find and the end users configure there browser to use our internal proxy servers. Users with the MAC OS X Anyconnect client can connect, they configure their Mac to use our proxy server, but the broswers will not work, clients can reach networks and resources behind the VPN gateway and have access to the Proxy(Tried a telnet to that hostname/port). Anyone run into this issue before? I am running ASA 8.3(2), Anyconnect(OS X) 3.1.01065.
Thank You

We had the same problem.
We are behind government firewall so I don't know which Cisco firewall is used but we are using AnyConnect to establish VPN from internet to LAN behind firewall. We have no problems with Windows. With Mac OS X connection through proxy didn't work with Safari and Chrome (both are using system Proxy setting), but it did work with Firefox (which has it's own Proxy).
Finally we found out that ethernet MTU size was the culprit. When we set it to manual, with size being 1347 (or less), proxy started to work.

SSL Certificate Mismatch with AnyConnect client

Hello,
We are having a problem with the AnyConnect client when connecting to our VPN. We are running the following:
AnyConnect v2.4.0202
(2 each) ASA v8.2(1) -- active/standby failover
AnyConnect Essentials Licensing
NOTE: We are not using certificates for authentication.
Primary clients: Windows XP and Windows 7
Problem
We have purchased an Entrust certificate for our ASA failover cluster called "vpn.company.com" and the it is attached to the outside interface on the ASA.
Steps to Reproduce
Install the AnyConnect (AC) client via https://vpn.company.com/. Connection occurs here without issue.
Once the AC client is installed and we try to use it in stand-alone mode (i.e., w/o hitting the ASA w/ a browser), a certificate mismatch occurs, and AC brings up the Windows/IE Security Alert dialog (see attachment CertError.jpg).
The user must press Yes to bypass mismatch.
PROBLEM: On Windows 7, the user must have administrative privileges and run the AC client as administrator -- otherwise, they get a dialog saying "Unable to establich VPN" (see attachment Unable.jpg).
The issue is we have a valid certificate that should be used for the connection. However, when looking at the connections made by the AC client with Fiddler, it would appear that the AC client is trying to connect directly to the ASA's IP address, and not the name. This is a nuisance for XP users, and a show-stopper for Win7 users as they do not have admin privileges.
I have not been able to find any documentation on Cisco.com relating to this issue. In short, how do I get the AC client to use "vpn.company.com" so there is no Cert mismatch?
Thanks,
-Matt

Tim,
I will read through the article more thoroughly; I've already been through parts of it -- won't hurt to go through again. I did initially have the IP address in my XML file, and immediately removed it when I noticed that it was using the IP address in the FIddler dump. It hasn't had any effect unfortunately -- even with uninstalling and re-installing the AC client locally.
The only other article/post I've come across on Cisco's site that comes close is here:
Cisco Support Community: ASA VPN Load Balancing/Clustering with Digital Certificates Deployment Guide
which seems to suggest that I will need a UCC certificate (which seems ridiculous) to do some of what I need to do. However the issue with that post is that it still wouldn't fix the issue where the AC client is using the IP address.
I will let you know if I find any smoking guns in the doco link you sent. Any other thoughts appreciated. I can't believe Cisco made the setup of the AC client this convoluted.
Thanks!
-Matt

AnyConnect Client v3.1 driver error on windows 7

Hello,
I used AnyConnect Client v3.0 on my windows 7 machine and worked well. But after automatic upgrade to v3.1 by the VPN server(ASA) and it does not work any more. It seems that VPN authentication is successful but activation of VPN adapter fails.
I see two error messages below:
The VPN client driver has encountered an error. Please restart your computer or device, then try again.
AnyConnect was not able to establish a connection to the specified secure gateway. Please try connecting again.

I already did most of suggestions below from google but still the issue has not been resolved.
- Rebooted the laptop
- Confirm ICS disabled
- Remove Anyconnect client from the laptop and reinstall

I am also facing the exact same issue. I even tried with the newer version. But it does not work. During connection, it asks for accepting the banner and the suddenly the cisco adapter driver gets uninstalled from device manager and cisco pops-up the error screen.
" the VPN client driver encountered an error. Please restart your computer or device and try again"
Please help.

Can anyone help me troubleshoot my VPN client issue, DART log attached

Hi all
I am having issues connecting with my anyconnect client, version 2.5 running Windows 7 64 bit
It keeps saying repairing vpn adapter, then encountered an error, there is no AV running, and I have reinstalled it many times
here is the log files
Can anyone help ?
cheers

Hello, there won't be a specific answer because so many things can cause that error.
You can try cleaning it...
http://www.discountofficeitems.com/technology/computer-accessories/cleaning-main tenance/cleaner-maintenance/fellowes-lens-cleaner/p28997.html
Occasionally a PRAM reset, CMD+Option+p+r will cure it...

Media is likely the biggest cause, might try burning at a slower speed.

Anyconnect Profile Issue

Hello,
I have 2 asa firewall in HA where I have created any-connect vpn profile for end users
All users profile are stored in flash as well as anyconnect client image
Suddenly due to some reason I need to shutdown my primary firewall
All things works good, secondary firewall came up,but no any connect user are able to connect their profile
When I see in ASA there are no profiles available in flash which I created in primary firewall
Its seems veired to me as both firewall config must be synced,..
Cn anyone help us what was the issue
or Should I need to create profile on both the firewall

AnyConnect profiles (and a few other things) are not automatically synchronized between ASAs in a failover pair. I'm not sure why Cisco has never fixed this but it's been a documented bug for quite some time.
You need to copy the files manually. They are small xml files and usually not too hard to copy.
If you've lost the primary unit altogether, you will need to recreate the profiles on the secondary active unit.

Anyconnect client and clientless connections hang for two users

ASA 5525, v. 9.1(5)19
Anyconnect client 3.1.02026
I have two users who are unable to connect via the AC client or clientless through the web portal. Using the client, it will get stuck in a loop of "checking for updates". On the portal, the connection will proceed to the point of "Cisco Secure Desktop successfully validated... Success.. Reloading..please wait." Then it hangs there.
The issue occurs for the user regardless of which company laptop she logs onto. A help desk tech can use her laptop and successfully connect, but she cannot connect on her own laptop or on another laptop. (Same for the other user.) So the issue doesn't seem to be related to her laptop or the AC installation. (Help desk did reimage her machine early in the troubleshooting process before they realized that the issue seemed to follow the user.)
I've updated the hostscan file - no change in results. Client and clientless connections seem to be working fine for all other users. We're stumped. Suggestions, anyone? thanks!

The LDAP should be server folks -- Active Directory. Chances are whoever manages the ASA's should have access to at least look in Active Directory to look that up. If they don't they need it.
I obviously don't know a lot about what devices you are using, but if you are using ISE, there should be some type of MNT device (Monitoring and Troubleshooting) -- which is collecting the logs and, hopefully, sending them to some type of syslog aggregate collection tool (splunk?).
Otherwise, there should be a device called a CAM (Clean Access Manager) that is collecting logs -- which may also be propagated to a syslog aggregate tool -- although with CAM's, you can pull the reports right out of them in a comma deliminated file (.csv) and go through them that way.
-- The thing that gets me is that it happens to two users no matter what computer they try to connect from, no matter what network they connect from, and other users can authenticate and gain network access on those same devices.
-- That is why it is rather perplexing. Pretty much saying it has to be something with:
- the IP pool they are getting an IP from
- their AD credentials
- their username
- something along those lines, if the information provided was fully accurate.

AnyConnect client no assigned address error

I am trying to set up the AnyConnect client (v2.4.0196) and when it tries to connect it fails with a no assigned address error. I look in the logs of the ASA and see a No IPv6 address available for SVC connection. IPv6 is disabled on the ASA.
Does anyone know how to prevent the AnyConnect client from trying to get an IPv6 address?
Thanks in advance...

Note that 2.4 is still beta, 2.3.2016 is the latest supported release today.
Having said that, I rather suspect an ASA issue than a client issue. Can you confirm whether or not an ipv4 address is assigned?
I.e. is there something in the logs like:
Oct 13 2009 09:05:55: %ASA-6-737026: IPAA: Client assigned 192.168.0.1 from local pool
Oct 13 2009 09:05:55: %ASA-6-737006: IPAA: Local pool request succeeded for tunnel-group 'DefaultWEBVPNGroup'
(note these are level 6 messages)

Anyconnect clients with intermittant timeout/high MS

I'm having a problem where some clients are pinging servers on my lan just fine, but every so often it hangs with about 2500-3000ms then continues just fine for another 30-40 pings. If I connect with another machine running the same version of Anyconnect (the latest version) it pings consistenty.
Noticing a lot of strange issues with Anyconnect recently - is there any server side logging that can be enabled to gain more insight on what's going on with specific clients? I had to reboot another ASA earlier today to remedy a problem where some new clients could connect but couldn't ping anything...while others would work like nothing was wrong...connecting/disconnecting like usual.
Thanks in advance

Hi,
I wil be difficult to figure out exactly what is going on without a TAC case but here are a couple of pointers that might help you to see what is going on:
1.) Filtered buffered logs on the ASA itself.
To verify if the traffic is dropped on the ASA or not, you can setup buffered logging:
logging buffer-size
logging buffered debugging
logging on
Then, check the IP address which is assigned to your AnyConnect client which is unable to pass traffic and check the entries related to it in the logs:
show logging | i
2.) Check the statistics of the AnyConnect session on the ASA
This command will show you a couple of counters related to your session and might give you a hint of what is wrong:
show vpn-sessiondb detail svc filter a-ipaddress
You can replace a-ipaddress by p-ipaddress or name if you want to filter on public IP of the client or username.
3.) Logs generated by the AnyConnect client itself
If you launch the event viewer from a Windows host where AnyConnect is installed ("eventvwr" command), you'll see that there is a new log type named "Cisco AnyConnect VPN Client". The client will write in there all the logs related to your connection.
If you are using Linux, the logs will either be stored under /var/log/messages or /var/log/syslog.
For OSX, it would be /var/log/system.log.
If you still don't see where the issue is after those steps. my advise would be to open a TAC case to have the issue investigated.

Nicolas
