Cisco VPN Issue - Split Tunnel Not Working

I am trying to configure Split Tunneling on my Cisco 3005 VPN Concentrator. The concentrator is running IOS version 3.6.7. The remote system I am trying to connect is a WinXP Pro SP1 system running version 3.6.3(A) of the Cisco VPN Client.

As a test, I disconnect my laptop from the network, dial my ISP manually, then establish a VPN connection using the Cisco VPN client. As long as I don't have Split Tunneling turned on (my group is set to 'tunnel everything'), all traffic passes through the tunnel fine.

The moment I switch on split tunneling (by selecting the "Only tunnel networks in the list" option), all tunnel traffic is discarded. In the VPN Client Status > Statistics page, I can see all of my internal networks (that I've defined in a Network List on the 3005) listed under "Secured Routes." Traffic destined for my ISP passes fine, but anything sent over the tunnel shows up as a discarded packet. There are very few encrypts and decrypts (if any), and I would imagine those that I'm seeing are tunnel maintenance packets.

I noticed one more thing that looks out of place that may be causing this problem. On the general tab of my VPN Client connection status, 'Local LAN access' is showing up as 'Disabled' even though I checked the box next to 'Allow local LAN access' when I setup the VPN connection. Not sure if this is normal or not, but it seems odd to me.

Any suggestions would be greatly appreciated.
