cisco PIX vpn connectivity woes

i'm pretty new to the pix world. i'm trying to learn a few things using various tutorials i've found on the net.

i have a pix 501 that i'm trying to use as a VPN endpoint. i have a winxp machine running vpn client 4.0.

here's the setup:

(internet)-----[cisco 831]-----[pix 501]-----(internal network)

i can connect to the pix and am assigned an IP address, but beyond this nothing happens.

i cannot look inside the internal network, and i cannot pass through the VPN to connect to the outside world either (browsing, etc).

here's my pix configuration. maybe someone can find something in here that will help.

i read someplace about something to do with a "split scope." while i wasn't really able to understand fully what that means, i gathered it had something to do with the pix dealing with two separate networks. is there some specific command that i need to implement? also, can someone give me the layperson's explanation of what this "split scope" does if it is the source of the problem?

Hello
Try posting in the Pix forum.If you don't get a reply I will send you a working basic config.

Hi,

'Split scope' is also known as 'split tunnel communications'. An example use of this is to enable a single device e.g. a PIX, to access both the Internet and be an endpoint for a VPN tunnel. An ACL is used to define which traffic goes through the tunnel and which traffic heads for the Internet. The permit statements identify the traffic to forward through the VPN tunnel and deny statements identify which traffic to forward outside the VPN tunnel to the next hop.
