Can't browse the Internet when connected to CISCO PIX VPN.
I have enabled the vpngroup split-tunnel command, but I am still unable to browse the Internet as referenced in the PIX configuration guides.

Snoopy13, have you had your coffee yet today?
>vpngroup PPTP-VPDN-GROUP split-tunnel 101
Makes no sense whatsoever.
If you are using vpdn group, meaning Microsoft PPTP client, you have no capability to apply a split-tunnel. Split tunneling is only for Cisco IPSEC VPN client.
You must simply un-check the "use default gateway on remote network" in the PPTP VPN Client Networking/TCP/IP settings.
Then, you will lose connectivity to your remote network because your VPN clients are on a different subnet, so you will have to add a static route on the client PC, something like:
C:\>route add 10.10.10.0 mask 255.255.255.0 192.168.240.100
Remote LAN MY VPN IP
The whole idea is that if a client connects to your network via VPN you don't want them to connect to anywhere else, especially the Internet because then they become an un-checked conduit between the Internet and your corporate LAN.

Just so i understand, aside from a static route on the client's workstation this can not be done?
What is the Cisco IPSEC VPN client? Is this just a matter of installing the Cisco VPN client on the workstation and using that as opposed to the MS VPN?

Yes. Because you are using a different subnet for your VPN client than your LAN, the client must either have a specific route entry for that subnet, or "use default gateway on remote network" checked
The Cisco VPN client is free for anyone that has a PIX. It is very simple to install and set up on the client, and takes a little extra config on your PIX. The VPN Wizard in the GUI makes it wicked simple.

Do i setup the VPN using the Cisco VPN Client 3.x or Cisco VPN 3000 Client 2.6?
Don't use 2.x
4.6x is the most current version that is compatible with XP SP2
Else, use whatever 4.x is avialable to you.
3.x will work if that's all you can get your hands on.

nat (inside) 1 0.0.0.0 0.0.0.0 0 0 covers all addresses. The nat (inside) 0 line is usually used for a no-nat access-list. So remove this line and try it.
