Anyconnect not passing traffic

[Brian Cartledge]

We have a problem with around 20 laptops after a recent upgrade from 2.5 to 3.1.05160. It works fine for the majority of users but these 20 laptops are able to connect but not pass traffic to the internal network. So login is successful, pinging from and to the client fails. Dart shows an error but I'm not sure if related -

Thanks,

Our team have the same problem, it's a blocker for us! We have a successful connect under CISCO AnyConnect 3.1.05160, but we couldn't open any resources, we couldn't access under Remote DeskTop, we couldn't ping any sites. Before this upgrade has come, everything was fine with 3.0 version and lower.

So, also CISCO AnyConnect isn't receiving packets now, so, may be it's root cause, but why it isn't?...

OS: Windows 7.

Sergey, is the issue affecting all of your users? For us it is only 20-30 laptops so it seems that the VPN configuration is fine but maybe a software issue with Anyconnect/Win7. 

[Sergey Vasilyev]

This problem affecting just several members of our colleagues. For most everything is fine. It makes me crazy. I've tried to reinstall software, reboot local machine, TCP\IP, disable all firewall, also, I've tried to install 3.0 version, cause everything was fine with it, but this version always tried to upgrade (

[Brian Cartledge]

It's possible to disable updates in the profile options.

Do you use Sophos A/V?

[Sergey Vasilyev]

Nope, we're using Dr. Web A/V. Will you be able to describe step by step, how is  it possible to disable updates and what is the profile in out case, where is it locate?

[Brian Cartledge]

sorry, I am pressed for time today to go into detail. But take a look on the FAQ for some info on how to turn off updates http://www.cisco.com/c/en/us/support/docs/security/anyconnect-vpn-client/107391-anyconnect-faqs.html

[Sergey Vasilyev]

Great, I've switched off autoupdate for CISCO AnyConnect and installed 3.0 version. So, it's working cool now, Brian, thanks you so much for your advise.

Now, we can wait answer from CISCO support here, but I think, it gonna be long waiting process :)

[Sergey Vasilyev]

Brian, good evening to you.

We've solved out problem. Open your VPN connection properties 'Cisco AnyConnect Secure Mobility Client Connection' and uncheck 'Connectify LightWeight Filter' (see attach for example)

[Brian Cartledge]

Hi Sergey, thanks for the advice. We had a similar filter for Sophos and unchecking this seems to have fixed the issue.

Hi Sergey, I encountered exact same issue and unchecking 'Connectify LightWeight Filter' solved the issue. Thanks for sharing the fix.

Hello Everyone,
OS: Windows 7
Sw: Cisco Anyconnect 4.0 secure mobility client.
I took more than 30 mns to troubleshoot the same issue, vpn connects successfully but no network access, i verified Event logs for this application in Event Viewer, i got "eventID 1 Encountered invalid network bound packet", and i followed your solution that is uncheck "Connectify LightWeight Filter". It worked fine.

Sergey, 

After auto upgrading operating system Windows 8 to Windows 10  had a similar problem. To solve the component "Azzouzi HotSpot LightWeight Filter" has been disabled on the wi-fi adapter and "Virtual Cisco Adapter".

Thanks for the advice.
