I'm pretty new working with the Cisco products, however I have the privledge to test the ASA 5520. I'm unable to ping the outside interface from the inside network. I'm unable to go out to the Internet. Any help is appreciated. Here is my config:

Hello XBSolutions
A pix does not allow you to traverse one interface and terminate connections on another. But to solve your problems with getting out here are the commands you can use to pat your inside and dmz networks out to the internet using the outside interface ip address.
global (Outside) 1 interface
nat (Inside) 1 192.168.0.0 255.255.0.0
nat (DMZ) 1 192.255.0.0 255.255.0.0
access-list inbound_in permit icmp any any
access-group inbound_in in interface outside
The access-list will allow your pings going out to respond back, everything else should now work fine. To watch your pings traverse the firewall execute the command "debug icmp trace".

If you noticed I changed the number for global from 0 to 1 so it would match your nat statements.

Thanks Patrick, I changed my config to match your sugestions. However, I'm still not able to get out or ping the Outside interface. Take a look below.

Hello,
try and add a default route to your configuration:
route outside 0 0 123.123.123.xxx 1
where the IP address 123.123.123.xxx is the address of the device directly connected to the outside interface of your ASA.
