Assuming you have the Router at the remote site.
The crypto ACL on Router would say :
access-list 101 permit ip any
This way all the traffic would be tunneled to the concentrator.
Now, you need to check if you have a TDG (Tunnel DEfaul Gateway) configured on the 3030. Also, check what device is configured as TDG ?
Once you confirm that, I'll let oyu knw the way to configure the Internet access.
Now, assuming, there's no TDG configured, then on 3030 you have to create an Interface PAT rule for the remote LAN.

Add the remote network there, and it shpold work fine.
Hope this helps.
