[Vpn-help] Cisco Client Access Rules

I am having problem using shrew vpn-client connecting to Csico Easy VPN with Dynamic Virtual Templates Interface (DVTI). I believe I passed both phase 1 and phase because I am assinged an IP address from the right pool and received DNS server IPs correctly (Let me know otherwise).  However, the routing does not work and I could not go anywhere.

I am excited about the latest release vpn-client-2.2.0-appversion.exe but it gives me the same result.

This VPN Server work fine with cisco-client on XP Pro.

Have anybody successfully configured The Shrew vpn-client with a Cisco Easy VPN, with or without DVTI? If so, could you please share with me your Shrew Client and Cisco Server configurations? Thanks!

Could anyone please help me diagnose my problem? Thanks!
