Hi,
You most likely need to enable icmp inspect in order to get icmp through the firewall. This is disabled by default
hostname(config)# policy-map global_policy
hostname(config-pmap)# class inspection_default
hostname(config-pmap-c)# inspect icmp
hostname(config-pmap-c)# exit
You should be able to connect to the Internet though (of course assuming your DNS settings are correct.
I hope it helps .. please rate helpful posts
