asked on ASA IPSec VPN from Windows to ASA 5510
Hi,
Today I setup a IPSec VPN on a ASA 5510. I was able to setup the DHCP for the client and get the client (Windows XP) to connect via the Cisco VPN Software. I'm having two general problems and was wondering if you could point me in the right direction. Unfortunately, I don't have the configure and left work with this problem on my mind.
1) Everytime I establish a VPN connection from the client and do an 'ipconfig' I see that my default gateway is the dhcp address assigned. So, I manually changed the default gatewa on the laptop to what should be the proper gateway.
2) I can ping the VPN client via the assigned DHCP address from my internal LAN but my client VPN PC can't ping anything internally.
I did try to setup a default tunneled gateway, but that didn't help. I know for a fact I didn't get to setting up any NAT or anything else. I had no other directions and time was running short.
Do you have any suggestions or step by step configuration settings I could follow for setting up IPSEC VPN that will allow for internal DNS to be used, proper routing to internal LAN, general setup,etc?
Thanks. I can't wait to get back to work tomorrow and get back to the grind.

I tried to enable split-tunnel, but i'm still having no luck with accessing the internet via the tunnel or local resources across the VPN. When I do a route print from the command line of the XP client using the VPN all the routes for the VPN network point back to the IP of the XP client.
172.20.2.x range is my private range on the LAN side of my firewall.
I'm uploading a my 'route print' display from my client PC when the VPN is connected. Also, i'm uploading my ASA configuration.
All my ACL are set to ANY ANY for testing purposes.

Thank you! I did notice a few minor problems, but I was able to fix them.
1) With the "objects" you had a .10 for the third octet. It should be a .0
2) By default the nat was added to the end of my nat list. In the ASDM i moved those two NAT commands to the top.
Thankfully now I can ping across in both directions! I do have some issues regarding why I can only PING and HTTP, but not RDP or File Share. I'll figure those out on my own. Thank you again.

It seems that you need to configure split-tunnel on cisco:
