I have a cisco vpn conentrator 3005. i can connect to via vpn just fine from the cisco client software but i cannot ping any local ips or any server names over the vpn. i do have the split tunneling turned on but cannot figure out why i cannot ping or browse network folders.

Can you check and confirm if the IP subnet of the client is same as the IP subnet of the network behind Cisco device; if yes, this is the problem. You would need to change the IP subnet at one of the ends.

Also, I would like to check if there is a firewall on the local machine which is interrupting with the traffic flow and finally you have allowed traffic on the concentrator to the remote users.

Thank you.

That is correct; they both cannot be 10.0.1.x/24

Thank you.

Sorry for the confusion; remote user access configuration is done on PIX/ASA not on concentrator.

Have you ensured that the client and network subnets are different.

Thank you.

No this is not what I meant when I specified that the remote clients should be on different subnet. Let me clarify:

Let's say a client "A" connects from home; he is having a Linksys router and the network he is on behind linksys is 10.0.1.0/24.
Noe let's say the user wants to create VPN to concentrator; he does that and as the network behind concentrator is also 10.0.1.0/24; he would successfully get connected but there would be no packet flow.

So, you need to change the IP subnet at one of the ends; normally we would change subnet at the Linksys end as it is easy to implement [but if you wish you can also change the IP subnet at concentrator end].
Please revert the virtual IP pool for the remote user on concentrator back to the range you had specified earlier [10.0.1.x]

Thank you.
