I am more familiar with IOS then the GUI that the 3000 series concentrators are using, which might be part of my problem.
We have a VPN concentrator on the edge of our network, with a dedicated line running to it.
The primary network used to be relying on Novell Directory Services, but it is being migrated to Active Directory.
There is a 3500 series router at the core with a stack of Cisco switches(no special ACL's on these)
When connecting using the Cisco VPN client to the network, any laptop will experience 100% packet loss to certain machines, and random loss(50%+) to the Windows DC's.
I have looked through the most of the settings on the concentrator but I have not been able to find much that would point me towards a solution.
The primary network is a 172 network, with the client vpn's being assigned a 192 network. Both are in a /24 range. We have the core router configured with a static route to the VPN concentrator incase this is the issue but I don't believe it should be.
Any assistance would be welcome.
