Check if you have NAT/NAT exemptions configured between the two interfaces ... also, did you try running the packet tracer to see what the firewall is doing with the packets? Do a test in both directions and see whether/where it fails ...

Can devices in the DMZ ping the DMZ default gateway address?  Does the log show any blocked connections if you try a constant ping from the DMZ to the inside network?

Like Garry said, do you have NAT setup (exemptions/static)? Also, a more complete (sanitized) config would be handy to determine what is wrong. Third, check the (ASDM) logs to see if anythings shows in there.

Hi ,

I have been through the configuration of your ASA 5520.Could you plz try the below configuration on ASA for traffic flow from Inside to DMZ.

ASA(Config-t)#access-group 101 in interface DMZ (and check whether ICMP is enabled on ASA in order to flow traffic ).
