VPN Problem after upgrading to SEP 11
We currently have a support case on this open but it isn't going anywhere so I'm looking to the user community for help. I have a hard time believing we are the only company who is having this problem.
We had SAV 10.1 and the Cisco VPN 4.7 client installed and working great. When the laptop is off the network the windows firewall is enabled and when the VPN connection is initiated the Cisco statefull firewall is enabled. Everything worked great until we started to upgrade to SEP 11. We only have the antivirus, antispyware, and proactive threat protection enabled. We do NOT have the Network Threat Protection enabled but have noticed that it still installs. Symantec told us that it is how the client communicates with the host server.
After upgrading the SEP 11 when we connect we get the error message from the VPN client: “The client did not match the firewall policy configured on the central site VPN device. Cisco Systems Integrated Client Firewall should be enabled or installed on your computer” and there is an error in the Event Log from the TrueVector Service stating: “TreuVector driver: Driver install or load failure: LoadNTDeviceDriver. Win32 error: The service cannot be started, either because it is disabled or because it has no enabled devices associated with it”
If we enable the Cisco Firewall (always on) there are errors that it cannot be found. We reboot the laptop, with the firewall enabled, and when Windows loads the errors are gone. We attempt to connect through the VPN and it works. We change the Cisco firewall to only enabling when we need it, reboot, and it fails again with the same errors listed above.
We have upgraded to the latest Cisco VPN client 5.0 and the MR1 for SEP11 and still get the errors. Has anyone else had similar problems? How have you resolved this?
