I having an issue routing traffic out of our cisco router out to the global internet. I have nat setup, I can ping to the outside interface from the inside network but traffic doesn't exit the router. Clean router with no access list, we can ping from outside but unable to access webpage. Any clues ?

Cisco config

Router#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
Router(config)#do show run

define your internal network:
access-list 100 permit ip any

bind it to outside interface:
ip nat inside source list 100 interface  GigabitEthernet0/0 overload

In addition to what SIM50 said, and assuming you didn't cut it out of the snippet you provided, you don't appear to have a default route pointing out of your Gig0/0 interface.  You won't get anywhere without that.
