AnyConnect secure gateway - IP forwarding table

[Felipe A. Amaya]

Hi everyone, we are receiving calls of users who are running Windows 10 and AnyConnect version 4.5.02036 that are having issues connecting to AnyConnect. The following is the message that is received.

The VPN client was unable to successfully verify the IP forwarding table

modifications. A VPN connection will not be established.

Now, in one case the computer was reimaged and the issue was resolved.  In some other threads they state that disabling the bonjour service was an option but this is not the case here also we search the registry for mdnsresponder but could not find anything.  Restarting and reinstalling the AnyConnect client had no effect.

Thank you in advance,

One more thing that I forgot to mention, when connecting to AnyConnect, the connection begins on WiFi which is the active connection and then suddenly it switches or displays or reads wired connection even though we are strictly connecting wireless.  We even try disabling the Ethernet connection as well as disabling IPv6 as some other threads suggested.  

Thanks very much,

Hi Jason,

To respond to your question....  No we could not find an answer, our solution at the end was to re image the windows 10 devices.  It is weird as we are using NAM with AnyConnect.

Good luck!
