VPN Client and packet duplication


I experience packet duplication on my workstation with the Cisco VPN client. My set up is as follows.

Windows 2000 Professional SP2

VPN 5000 client v.5.1.10 3DES

The packet duplication only occurs when NOT using the client. For example just browsing the web or pinging. Upon initializing the client the duplicaiton ceases until my session ends. Any non VPN sessions result in packet duplication. I have been able to reproduce the problem on 4 other machines, each with a different NIC. The only common factor is Windows 2000 Pro and VPN client for Win2K.

Windows 95/98/NT machines do not experience this issue. I can only assume it has to do with how the client is bound to the adaptor in Win2K.

Anyone else familiar with this issue please pass on info.

thanks in advance for any help,

Re: VPN Client and packet duplication

I don't have an answer for you, but I do see the same issue on Win2k boxes with the VPN client, just so you don't think your alone in the world.

Re: VPN Client and packet duplication

Just an update,

I have a ticket open with Cisco on this issue, but have not heard anything back. They had me upgrade the client through several revisions, with no success.

Hope something comes down soon as this is a major pain and interference.
