There is a setting in the VPN connection under the TCP/IP element that will be checked - uncheck use Default Gateway on remote network and problem goes away.
Start, run, ncpa.cpl (enter).  Right-click the vpn connection and choose properties.  Click on the Networking Tab, then on the TCP/IP properties and click on Advanced button.  Uncheck use default gateway on remote network.

Not sure how the Cisco settings differ to Windows - but there will be a similar option in the Cisco software.
You may need to get your IT department to re-configure the policy to allow you internet access and re-configure your computer with the new policy.

I assume you are using the Cisco VPN client?
All VPN clients have a security feature in that that blocks local connections, including local Internet access, to protect the office/remote network to which you are connecting. This prevents neighboring systems from possibly being able to gain access through your VPN connection to the remote network. To get around this and allow simultaneous connection to your local network and Internet at the same time as having access to the VPN site, you need to enable split-tunneling. With the Windows client you are able to do so your self within the VPN client by un-checking  "Use default gateway on remote network", but with the Cisco client the only option is to have VPN administrator enable split-tunneling within the VPN appliance configuration. Due to the security concerns mentioned the administrator may not be willing to do so.

On a Cisco Concentrator 3000, it appears that split tunneling is enabled?  Any specific ideas?
BTW, it will work with the windows client with the Default Gatway option unchecked.
Alan HardistyCo-OwnerCommented:
Split tunnelling may not be enabled on the client policy, thus it won't work.
I'm not a Cisco guru though, but that's my best guess.
