Cisco ASA 5510 config issue 8.0(2) - No internet traffic

Hello,

I'm trying to configure a Cisco ASA 5510 so the inside clients can access the web.

The setup is a ADSL2+ connection --> Cisco 877 in full bridge mode --> Cisco ASA 5510

I can ping the internal PC's, I can ping the Gateway IP but I cant ping the outside world or access the web.

Here is my config:
