The problem is I can ping the DNS with success, but i cannot ping any website by name. I get an ip address on the client, but the client has no internet access.

I would appreciate any help that i could get to understand what i am missing.

There are several things about your environment that I am not clear about. But let me start some explanation from this statement " I get an ip address on the client, but the client has no internet access". I see that the interface uses this acl

ip access-group Internal_ACL out

There are permit statements for addresses inside the network. The only permit for any external address is

permit tcp any any eq www

 I am puzzled why www  would be defined as the destination port. I would think that it would be better if it were the source port. As it stands the config would deny any traffic from outside to the client network that was not an http request to an inside address. So no ping, no https etc.
