An error when trying to connect with the Cisco AnyConnect.

[MariyaPetler]

Good day!

I connect from Windows 7 (also from Ubuntu) with the Cisco AnyConnect client 3.0 (and with Cisco AnyConnect Secure Mobility Client 3.1) and  get error a “The VPN client was unable to successfully verify the IP  forwarding table modifications. A VPN connection will not be  established.   No changes had been made to the  configuration  of my  asa5520 running 8.4(2) (ASDM 6.4(5)).

I have license  (AnyConnect Premium Perpetual) supports 2  vpn connections.

I read about this problem on different forums and cisco.com:

disabled unused adapters, check install software (Adobe photoshop and Bonjour are not installed on my system).

I made new configuration AnyConnect  in ASDM. But the problem remains the same...

Please, help me find the way to solution in this situation!

I have seen that error before but it usually clears up on its own.  I have a working theory though so perhaps this might help you.  I noticed that once you connect, 2 files are created in C:\ProgramData\Cisco\Cisco AnyConnect VPN Client.  I think that folder is different if using v3.x instead of 2.5.  Anyway, the files are routechangesv4.bin and routechangesv6.bin.  Try deleting each and then rebooting.  Try connecting again after that.

My theory is that those files are not clearing up after disconnecting.  I think they are supposed to go away after disconnecting but I noticed in some cases that they don't.

Thanks for the advice, but unfortunately there are no such files neither Ubuntu  no windows 7...
