Pix VPN Issues - client w98 cannot access network

[donchr]

Question:

I have multiple Pix to Pix Vpn connections up and running. But I can't seem to get pptp client access to work. I can establish a tunnel between w98 client to pix. I'm issued an IP address 192.168.100.1 out of the pool. The problem is I can't see (ping) any inside devices on my network. The only thing I can ping is the outside address to the PIX.
What am I forgetting?

Thanks for the help!
