I am desperately trying to put my Cisco ASA 5505 up to accept ping requests from the Internet and my DMZ. On my LAN, I have some monitoring software running using ping to see if various machines are running (both physical and virtual machines). It is therefore very important that I can use ping anywhere on my LAN and DMZ as well as the Internet.
Right now, I only get a timeout message. What do I need in my setup?

This is my running config:
