ASA can ping outside, but internal users cannot access internet
What am I missing here? The ASA 5512 can ping 8.8.8.8, but anyone on the inside interface cannot get out. I am rather new to the 8.3+ syntax, so I was wondering if anyone could help me out?

Yeah I fixed the 0/0 port shutdown. The NAT commands are all different now...very frustrating.

Hevnkva - so it will look like the following?
obj-obj-192.168.47.0
nat (inside,outside) auto source dynamic
Is that correct?
obj-obj-192.168.47.0
nat (inside,outside) auto source dynamic
Is that correct?
No, just enter the line as one in the config mode.
Here is a good guide for new NAT configuration for ASA 8.3 >

Alright the ping works from the internal interface, but I do not get a reponse. Meaning I can ping google.com and it does a DNS lookup, but the pings fail - why would this be?
you will have to inspect ICMP :)
http://www.fir3net.com/Cisco-PIX/pix-asa-how-to-enable-icmp-inspect.html
http://jklogic.net/cisco-asa-and-icmp-configurations/ Solution 3:
Solution 3: This is a bit more complex, but will allow higher security level interfaces to ping/trace route lower security level interfaces without the use of access-lists. To do this, we will tell the ASA to inspect icmp in a service policy. If you are using a ASA, you should have a default policy in the base config called global_policy.
global_policy:
FW-ASA(config)# policy-map global_policy
FW-ASA(config-pmap)# class inspection_default
FW-ASA(config-pmap-c)# inspect icmp
