Cannot ping inside host from DMZ using asa5505

iamarsin64 — Tue, 12 Mar 2019 05:47:24 GMT

I have inside network 172.16.0.0/24 , 172.16.1.0/24 , 172.16.2.0/24 , 172.16.3.0/24 ,it connect to a layer3 switch.

Layer3 switch connect to asa,network address is 192.168.0.0 /30.

DMZ network address is 172.16.4.0/24

My inside network can go outside to internet and go to DMZ watch the web page.

But DMZ can't go to inside network to get domain or inside server's service.

What should i do to my running config.

Here is my asa running config:
