No idea...none of us here know how you've got your DMZ set up, what firewall(s) you have in place, what protocols you're filtering, etc. Could be any one of a thousand things.
As a rule, though, ICMP is one of the first protocols you turn off from the outside world, to prevent someone running a ping sweep, to see what devices are there. Once they get addresses, they can start to dig deeper. You say you can't ping it...does it work otherwise??
