Lost connectivity after vpn authentication.

Got VPN going on my pix 501. I know the vpn client acts like a personal firewall, but I'd like to still have internet connectivity after authenticating to the firewall. I can't reach anything other than my internal network from across the internet. I request time out after pinging a site. Here's my config:

Any help would be greatly appreciated.
 
Using IPSec, you must enable split tunneling to be able to access the internet and VPN at the same time.

Add this line to your vpngroup..

vpngroup agents split-tunnel <ACLName>

Then add this ACL

access-list <ACLName> permit ip any <VPNPool Network> <netmask>

Thanks for the info LloydSev, only now I can't access my internal network. All that Split-Tunneling is doing is removing the DFG from my client's vpnpool ip address. When that happens, I can see the rest of the cloud, but there's no way for my client to see the internal network. The DFG of my client is using itself for the vpnpool ip address. Is there any way to set the DFG to something else other than itself to see both the internal network and the cloud ? Here's my config:
