Hi Genious..
I have built up the new DMZ zone on my firewall and couldn’t access/receive ping responses to Its IP X.X.236.97 from inside interface connected hosts.
Currently there is no ACL applied for DMZ3. Im looking for communication from inside interfaces host to DMZ3 interface IP where it is not working? What would be the issue am I missing anything Basics here. The acl applied to inside interface is allowed for any ip to ip communication.
interface TenGigabitEthernet1/3.782
description DMZ3
nameif DMZ3
security-level 40
ip address X.X236.97 255.255.255.224 standby X.X236.98
interface Inside
description Global Inside
nameif Inside
security-level 100
ip address X.X249.161 255.255.255.248 standby X.X249.162
HYD-5585X-ASA/Global# sh nameif
HYD-5585X-ASA/Global# sh nameif
Interface Name Security
Outside Outside 0
Inside Inside 100
TenGigabitEthernet1/3.782 DMZ3 40
HYD-5585X-ASA/Global#
ACL permitted:
access-list Inside_access_in extended permit ip any4 any4
HYD-5585X-ASA/Global# sh run | in access-group
access-group Outside_access_in in interface Outside
access-group Inside_access_in in interface Inside

1) is there a route to the DMZ subnet ?
2) even if there is a route you cannot ping across the firewall to another interface ie. you can ping the DMZ interface IP from the DMZ but not from the inside or coming in on any other interface. This is a built in security feature on the firewall.
To test you need to try and ping from the inside a device in the DMZ not the DMZ interface IP.
